 While writing the screenplay , Hirani and Joshi stayed together for more than four months . They developed scenes by going out for a walk and discussing the scene . They would not return home until they had created a scene that would make them laugh , or cry , or had some provocative thought . While there was a shortage of resources during the shooting of Munna Bhai M.B.B.S. , the crew did not encounter a financial crisis during the filming of Lage Raho Munna Bhai , as the team managed to receive whatever was deemed necessary ( including a Jimmy Jib , a specific kind of camera crane , just for a single crane shot ) . The film was shot on location in and around Mumbai , with Goa as a backdrop for the " Aane <unk> " song .
