Rajkumar Hirani revealed that he has five half-finished scripts for 'Munna Bhai 3'. "There's a Munna Bhai LLB, Munna Bhai Chal Base, Munna Bhai Chale Amreeka, and more," he added. Hirani further said he is working on a unique idea now. "The most important factor is that the next instalment has to get better than the previous films," said Hirani.
