During the shooting of 'Mumbai Express', lead male actor Kamal Hassan injured his wrist badly. He plays a role of stuntman in the film, decided to do all the stunts by himself. He was hurt in a motorbike scene. "It is a professional hazard, and you can't help it. It's quite challenging to be extra precise when you set out to do stunts. It isn't something new to me. I like to do innovating things, and if that contributes to making a better film, why not!" he explained. Even he didn't allow the director Singeethan Srinivasa Rao to cancel or delay the shoot.
