Sanjay Dutt, Arshad Warsi, and Rajkumar Hirani recently reunited, leading to speculation about a 'Munna Bhai 3'.
They were actually shooting a commercial for a hospital, not a new film.
Rumors started after a behind-the-scenes video of the ad shoot was released online.
A source claimed 'Munna Bhai 3' may 'never' happen due to a fallout between Hirani and producer Vidhu Vinod Chopra.
Previously, a film titled 'Munna Bhai Chale America' was shelved without reason after its script was finalised and pre-production started.
Despite the success of 'Munna Bhai M.B.B.S' and 'Lage Raho Munna Bhai', Arshad previously stated that a third installment may not happen.
