Voice actors Dave Franco, Manny Jacinto, and Jenny Slate discuss their experience working on the animated fantasy film Forgotten Island. The actors explain how the lengthy animation production process—spanning over five years—means they record their dialogue early and remain largely disconnected from the final product until its completion, allowing them to experience the film like regular audience members. Franco notes that whilst actors spend relatively little time in the recording booth (he attended 8-10 sessions), the directors have invested years in bringing their vision to life.

The three actors voice characters from Filipino folklore: Franco plays Raww, a charming were-dog; Slate voices Batiba, a glowing catlike demon; and Jacinto portrays Bungi, a three-eyed demon baby. Each actor was surprised and impressed by the final animation quality, with Slate particularly enjoying how her character illuminates during magic, and Jacinto noting how the animators brought emotional depth to the voice work. The actors discuss their different performance approaches, from Franco's playful work on a comedic Dragon Ball Z-style sequence to Slate's careful balancing of her character's hidden motivations and Jacinto's restraint in avoiding excessive comedy.
