Filmmaker Rajkumar Hirani has revealed that he is working on the third instalment of his famous “Munna Bhai” franchise.

Rajkumar Hirani made his directorial debut with Munnabhai MBBS in 2003 and was a hit at the box-office. It was followed by a successful sequel, 2006’s “Lage Raho Munna Bhai”. The third part was announced a few years ago but it is only now the director has cracked its script.

“We are working on ‘Munnabhai’ third part. After several years we have cracked an exciting idea… it is of that level. The third part of the film has to be better than the previous one. We have got a script of a calibre,” Hirani said on the sidelines of MAMI festival here.

It will bring back the adorable pair of Sanjay Dutt and Arshad Warsi, who essayed the role of Munna and Circuit respectively in the first two films.

“When we write, we do not think of casting. We are making third part of ‘Munnabhai’ and it will definitely have Sanjay and Arshad. Writing should be free flowing. We are still writing the script, we have not reached casting yet (for other actors),” Hirani said.
