However, sources from Vinod Chopra Productions say that the script for Munnabhai 3 is not yet finalized and Vidhu Vinod Chopra is in the habit of not finalizing the cast only when the script is ready in all respects and okay-ed for production.
It is believed that Rajkumar Hirani writer-director of Munnabhai MBBS and Lage Raho Munna Bhai has a draft of the Munnabhai 3 script which he wrote even before 3 Idiots happened. In fact, the tentative title of the franchise is Munnabha Chale Amerika.
Bollywood observers say that Aamir, after finishing Katgi’s untitled film, will be busy with Yash Raj Films Dhoom 3 until the third quarter of next year. So if Aamir has to be Munnabhai, the film will only start towards the end of 2012.
