Who is Briella Guiza? Meet the actress playing Mia, Coral’s best friend, in Disney’s upcoming Aquamarine sequel series.
Briella Guiza is gaining fresh attention after being announced as part of the cast of Disney’s upcoming Aquamarine sequel series.
The actress will play Mia, a close friend of Coral, the teenage daughter of Aquamarine and Raymond. The new project revisits the world of the 2006 film while introducing a younger generation of characters and a new mystery connected to the missing mermaid Aquamarine.
While Briella Guiza may not yet be a household name, the Aquamarine casting announcement has introduced her to a much wider audience. She has previously appeared in projects including The Rookie, Criminal Minds, Station 19, Atlas and Ambulance, according to entertainment reporting and filmography listings.
So, who is Briella Guiza, what role will she play in the new Aquamarine series, and what do we currently know about her acting career?
Who Is Briella Guiza?
Briella Guiza is an actress whose profile is growing following her casting in Disney’s upcoming Aquamarine sequel project.
She has appeared in several television and film productions before joining the new Disney series. Public filmography listings associate her with projects such as Atlas, Ambulance and Station 19, while recent reporting also mentions appearances in The Rookie, Criminal Minds and Matlock.
Her role in Aquamarine could become one of her most visible projects yet because the series is connected to a film that has maintained a nostalgic following since its release in 2006.
However, there is an important difference between what is publicly confirmed and what is simply repeated across biography websites. Detailed information about Briella Guiza’s age, birthday, family background and private life is not extensively documented in the recent reporting surrounding her casting.
For that reason, the most reliable way to understand her rising profile is through her confirmed acting work.
Briella Guiza Will Play Mia in Aquamarine
In the upcoming Aquamarine project, Briella Guiza will play Mia, Coral’s best friend.
Coral is the daughter of Aquamarine and Raymond and is played by Kenzi Richardson. The new story follows Coral as she moves to a seaside town, begins investigating the mystery surrounding her mother’s disappearance and discovers that she has her own connection to the mermaid world.
Mia is described as an edgy, funny and fiercely authentic friend whose intelligence, creativity and outsider confidence challenge Coral’s desire to fit in.
That description suggests that Mia could play an important role in Coral’s coming-of-age journey.
Rather than simply being a background character, Mia appears to be part of the central group surrounding Coral as the young protagonist tries to understand her identity and the secrets connected to her family.
What Is the New Aquamarine Series About?
The new Aquamarine project is not simply a scene-for-scene remake of the 2006 movie.
Instead, it continues the story years later.
The new pilot centers on Coral, a teenager who moves to a dreamy seaside town and begins uncovering the truth about her mother’s disappearance. During that journey, Coral discovers that her mother was a mermaid and begins developing magical abilities of her own.
This creates a direct connection to the original movie.
In the 2006 film, Aquamarine was the mermaid at the center of the story, while Raymond was the lifeguard who became an important part of her experience in the human world.
In the new series, Coral is their daughter.
That makes the next chapter both a continuation of the original story and a new coming-of-age fantasy centered on a different generation.
How Is Briella Guiza’s Character Mia Connected to Coral?
Mia is Coral’s best friend and one of the key new characters in the Aquamarine story.
Coral is described as thoughtful and artistic, but she is also trying to understand where she belongs as she discovers her unusual family history.
Mia’s personality appears to provide an interesting contrast.
According to the announced character description, Mia’s confidence and outsider perspective challenge Coral’s desire to fit in with the people around her.
This could make their friendship an important part of the show’s emotional story.
The original Aquamarine was strongly associated with friendship, particularly through the relationship between Claire and Hailey. The new project appears to continue exploring friendship while giving a new generation of characters their own personalities and conflicts.
Mia may therefore become one of the characters helping Coral navigate both ordinary teenage challenges and the extraordinary discovery that she is connected to the world of mermaids.
Briella Guiza’s Previous Movies and TV Shows
Before her Aquamarine casting, Briella Guiza had already appeared in a number of screen productions.
Her publicly listed credits include:
- Atlas
- Ambulance
- Station 19
Recent entertainment reporting has also associated her with:
- The Rookie
- Criminal Minds
- Matlock
Appearing across different productions can help a young actor develop experience in different types of storytelling and audiences.
For Briella Guiza, the Aquamarine role is particularly interesting because it connects her to a recognizable entertainment property with an established fan base.
Why Is Briella Guiza Getting More Attention?
The biggest reason is the announcement of the Aquamarine sequel series.
The original film developed a strong nostalgic audience over the years, particularly among viewers who grew up watching the movie during the 2000s.
The decision to revisit that world has therefore attracted attention from both longtime fans and a new generation of viewers.
The new cast includes Kenzi Richardson as Coral, Briella Guiza as Mia, Theodore Dalton as August and Annika Reese as Paige. Jake McDorman will return as Raymond, while Emma Roberts is set to return as Claire Brown in a guest role and also serves as an executive producer.
Being part of this new ensemble puts Briella Guiza in a project that already has built-in audience interest.
For viewers unfamiliar with her earlier work, the series may become their first major introduction to her.
A New Generation of Aquamarine Characters
The original Aquamarine focused on Claire and Hailey, two friends whose lives changed after a mermaid named Aquamarine entered their world.
The new project moves the story forward by introducing Coral, Aquamarine’s daughter.
Around Coral is a new group of young characters.
Briella Guiza as Mia
Mia is Coral’s authentic and outspoken best friend.
Theodore Dalton as August
August is a surfer who develops a connection with Coral.
Annika Reese as Paige
Paige is described as the stylish queen bee of the beach club, although the character is not being presented as a simple or stereotypical “mean girl.”
Together, these characters create a new social world for Coral.
The structure allows the project to preserve connections to the original movie while developing an entirely new set of friendships and relationships.
Jake McDorman’s Return Connects the Old and New Stories
One of the most significant announcements surrounding the project is the return of Jake McDorman.
McDorman played Raymond in the original Aquamarine movie.
In the new series, Raymond is now a single father raising his teenage daughter Coral while dealing with the disappearance of Aquamarine.
His return creates a direct bridge between the original film and the new characters.
For Briella Guiza and the other younger cast members, this means they are joining a project that combines returning performers with a new generation.
That combination is one reason the casting announcement has generated significant interest.
Emma Roberts Is Also Returning
Emma Roberts, who played Claire Brown in the original movie, is also connected to the new project.
She is expected to appear as Claire in a guest role and is involved behind the scenes as an executive producer.
The return of Roberts and McDorman gives longtime fans familiar characters to follow.
At the same time, the new cast—including Briella Guiza—will be responsible for introducing the next chapter of the story.
This balance could allow Aquamarine to appeal to audiences who remember the original film as well as younger viewers discovering the story for the first time.
What Happened to Aquamarine?
One of the central mysteries in the new series involves Aquamarine’s disappearance.
The announced premise states that Coral begins investigating what happened to her mother and eventually discovers the truth about her own half-mermaid identity.
However, there are still unanswered questions.
It has not been confirmed whether Sara Paxton, who played Aquamarine in the original film, will return to the project. Joanna “JoJo” Levesque’s involvement has also not been confirmed.
This uncertainty has naturally led to fan discussion about what the series could reveal.
However, theories from social media and fan communities should not be treated as confirmed plot information.
The most reliable information currently available comes from the announced premise and casting details.
What Fans Are Saying About the New Aquamarine
The announcement has already sparked discussion among fans online.
A Reddit thread sharing the casting news included reactions ranging from excitement about the return of Jake McDorman to questions about what happened to Aquamarine and whether the original story will be changed. These comments reflect fan reactions and theories, not confirmed production details.
This kind of discussion demonstrates the advantage of revisiting a film with a strong nostalgic following.
People who watched Aquamarine when it was released now have questions about where the characters’ lives have gone, while newer audiences may be discovering the story through the upcoming project.
For Briella Guiza, joining such a recognizable franchise could significantly increase public interest in her career.
Is Briella Guiza the Main Character in Aquamarine?
No. Based on the currently announced premise, Coral is the central young character in the story, and she is played by Kenzi Richardson.
However, Briella Guiza’s character Mia appears to be one of Coral’s closest friends and part of the main new ensemble.
The project has announced Guiza as one of its regular cast members, alongside Richardson, Theodore Dalton and Annika Reese.
That suggests Mia will have a continuing role in the story rather than appearing only occasionally.
The exact size of her role and future character development have not yet been publicly revealed.
Is Briella Guiza a Rising Actress?
Based on her growing list of screen credits and her casting in a high-profile Disney project, Briella Guiza is an actress to watch.
However, “rising star” should not be confused with an established global celebrity.
Her career is still developing, and much of the new public attention around her comes from the recent Aquamarine announcement.
That is exactly why this moment is important.
New casting announcements often create a search opportunity because audiences immediately begin asking questions such as:
- Who is Briella Guiza?
- What has Briella Guiza appeared in?
- Who does Briella Guiza play in Aquamarine?
- What movies and TV shows has she been in?
An article that answers those questions clearly can be more useful than a generic celebrity biography filled with unverified information.
What Is Known About Briella Guiza’s Personal Life?
Publicly available reporting about Briella Guiza currently focuses primarily on her acting work.
Detailed information about her age, birthday, family, education, relationships and personal finances is not extensively documented through the recent reliable sources covering her Aquamarine casting.
For that reason, it would be misleading to fill an article with unsupported details simply to create a longer celebrity biography.
The available evidence supports focusing on:
- Her acting career
- Her publicly listed credits
- Her casting as Mia
- Her role in Disney’s upcoming Aquamarine project
As her public career develops, more information may become available through interviews, official biographies or direct statements.
Until then, separating confirmed information from speculation provides readers with a more trustworthy profile.
When Will the Aquamarine Series Be Released?
An official release date has not yet been announced.
Disney+ and Disney Channel ordered a pilot for the project, meaning the production is still at an early stage and a full series release should not be assumed until further announcements are made.
This distinction is important.
A pilot order does not automatically guarantee that a complete season will be produced.
Fans will need to wait for additional information about whether the project receives a full series order and when it may eventually be released.
What Could Aquamarine Mean for Briella Guiza’s Career?
The project could introduce Briella Guiza to a significantly larger audience.
Aquamarine is connected to a film that has remained recognizable for approximately two decades, and the involvement of Emma Roberts and Jake McDorman gives the new project an immediate connection to the original cast.
At the same time, the new characters—including Mia—will need to establish their own identities.
That creates an opportunity for Briella Guiza to become associated with a new generation of the Aquamarine story.
Of course, the future of the project depends on its development beyond the pilot stage.
For now, the confirmed information is that Guiza has joined the cast as Mia, Coral’s best friend.
