Ritesh Deshmukh is doing a walk-on part in Karan Johar's 'KANK'. He has no regrets for it. He says, "At least I got a chance to be directed by Karan and to be in a few frames with Rani Mukherjee. It's a film that one is proud to be part of in any capacity, visible or invisible. Mine was never meant to be a full length role." He will do it again as Karan is a very good friend of him.
