Seeing Sanjay Dutt coming to film sets and working despite battling cancer literally increased 'Shamshera' director Karan Malhotra's respect for the former.

Sharing how Sanjay silently braved the illness without letting anybody know about it during the film shoot, Karan said, "The news that Sanjay sir had been diagnosed with cancer came to all of us like a huge shock. We had no idea about it. He was talking, behaving, and working as if nothing has happened. I guess that's why he is where he is today, having conquered this too. Sanjay sir doesn't let anything get the better of him. He is an inspiration on the sets for everyone."
