 Hirani admitted in an interview that he felt the burden of expectation while writing the screenplay for Lage Raho Munna Bhai , as he had to create " something to match " the first film . Initially there was some effort to incorporate scenes or characteristics of the first film into the sequel ( such as the idiosyncratic laugh of Dr. <unk> , portrayed by Boman Irani in the first installment ) , but the risks of repetition were consciously averted .
