The animated feature introduces a diverse cast of characters, including the standout figure of Mermahn, the Prince of Kataw. Voiced by Kevin McCann, Mermahn is depicted as a charismatic yet somewhat self-absorbed merman, whose journey intertwines with that of the protagonists. Directors Joel Crawford and Januel Mercado shared exclusive details about Mermahn's role and the creative decisions behind his character, highlighting McCann's exceptional vocal performance which was retained from the initial scratch recordings. This unique casting choice underscores the film's commitment to authentic and dynamic character portrayal.

Further insights from the directors reveal a deliberate effort to push the boundaries of 2D animation, incorporating anime-inspired aesthetics and narrative elements. The creation of Nakali, the mystical island where much of the story unfolds, allowed the team to experiment with camera angles and lighting design, aiming to immerse the audience in a distinct 90s-era color palette and atmosphere. This artistic direction promises a visually rich and nostalgic experience, setting "Forgotten Island" apart from contemporary animated films.

The narrative of "Forgotten Island" revolves around Jo and Raissa's accidental transportation to Nakali, an island teeming with magical and mythological creatures from Filipino folklore. As they navigate this wondrous yet perilous realm, they encounter allies such as the weredog Raww, voiced by Dave Franco, and confront formidable adversaries like The Dreaded Manananggal, brought to life by Tony-winning icon Lea Salonga. The central conflict intensifies as the friends discover that their cherished memories are the price of returning home, compelling them to race against time to preserve their bond and find a way back.

The film boasts an impressive vocal ensemble, featuring talents such as HER as Jo, Liza Soberano as Raissa, and a host of other acclaimed actors including Manny Jacinto, Jenny Slate, Dolly de Leon, Jo Koy, and Ronny Chieng. Each actor contributes to the rich tapestry of characters, bringing depth and personality to the inhabitants of Nakali. This stellar cast, combined with the innovative animation and compelling storyline, positions "Forgotten Island" as a must-see cinematic event.

In essence, "Forgotten Island" is not merely an animated film; it is an ambitious artistic endeavor from DreamWorks Animation, showcasing a blend of visual innovation and heartfelt storytelling. With its September 25th release, the movie is poised to offer audiences a captivating escape into a world where friendship, memory, and mythical adventures intertwine, all presented through a fresh and dynamic animation style.
