The '4th Idiot' is not a sequel to Rajkumar Hirani's '3 Idiots' but just an inspiration of the movie. It is an animated film that will entertain the kids and the adults alike. The film is produced by Biswaroop Roy Chowdhary. It has a completely new story and a new cast but the only thing that will be part of the new movie from the old one is the voice accent of 'Chatur Ramalingam'.
