Kurush Deboo has spent most of a working life as an actor whose name has been turning up in credits for decades. Comedy keeps coming back on the credit list. 45 credits across 37 years is a rate most careers never reach. 'Munna Bhai M.B.B.S.' sits at the front of the filmography, where he plays Dr. Rustam Pavri. 'Lage Raho Munna Bhai' belongs on any short list of his work. The career opened quietly, the way most long ones do.
