Sushmita has been away from the silver screen for a long time now but she was not away from some action in life for sure. She is all set to bounce back with David Dhawan's Do Knot Disturb and she is pretty excited that it would be a comedy film which would mark her comeback into the industry. She feels that doing serious films do take on the emotional toll on a person and comedy is the best way to relive one from the stress.
