Indian actor Irrfan Khan has refused a part in a Steven Spielberg film because he didn39t find "enough meat to explore" himself as an actor."I felt the character did not have enough meat to explore myself as an actor. Hence, I said no... Else who wouldn39t want to work with Steven Spielberg?" Irrfan said in a statement.The "Slumdog Millionaire" and "Life of Pi" actor was offered to work in a Spielberg film, which also had Hollywood actress Scarlett Johansson in it.Sharing that it is more than a dilemma for him to choose or deny films, Irrfan said: "I am at a stage in my career where I am trying my best to surprise my audience with every role and give them some. I am hoping the future holds something so path-breaking and so empowering for me as an artiste that no will not be an option."
