Yes, a live-action adaptation of "FernGully: The Last Rainforest" has been announced. In 2021, it was reported that a new film based on the beloved animated classic is in development, with plans to modernize its environmental themes. However, details about the cast, release date, or specific production schedule have not been widely disclosed yet. Fans of the original film are eagerly awaiting more information on this project.

Disney reportedly tried to stop "FernGully: The Last Rainforest" due to concerns that the animated film would compete with their own animated features, particularly "Aladdin," which was released around the same time. Disney executives were worried about the potential impact on box office performance. They also raised issues regarding the marketing of "FernGully," which they believed could lead to confusion among audiences. Ultimately, Disney's attempts to halt the film were unsuccessful, and "FernGully" was released in 1992.

"FernGully: The Last Rainforest" has often been compared to "Avatar," directed by James Cameron. Released in 2009, "Avatar" features themes of environmentalism, the impact of industrialization on nature, and the conflict between a native culture and external invaders, which parallel the storyline of "FernGully." Critics and audiences noted similarities in the narrative structure and ecological messages, leading to discussions about how "Avatar" may have drawn inspiration from or had elements reminiscent of "FernGully."

However, there is no official "FernGully 3." While there have been discussions and rumors about further sequels or potential reboots, no additional films have been produced as of now. The franchise remains primarily known for the original 1992 film and its direct sequel.
