'Caliber' event in Los Angeles
Sarkar is also the director of development at Johnny Depp's production company, Infinitum Nihil, and is an interesting guy to chat with. (That Depp company is partnering in the planned "Caliber" film and I wouldn't be surprised if Depp shows up somewhere in the cast as well.)
I wouldn't be surprised if Johnny Depp played the lead Indian role in the Caliber movie. He doesn't seem to have any qualms about playing Indians.
