Roth tackled Edward Norton as the green giant in the 2008 movie, playing villain Emil Blonsky.
The star admits he has been contracted for three Hulk movies, and hopes Hollywood executives pick up the option for a sequel as he had so much fun shooting the action picture.
He tells MTV.com, "I don’t know if they want to bring (my character) back, but I told them I’m absolutely game for it. It would be so much fun to do it again. I’m in it for three.
"I had the best time ever with that one - more fun on set than anybody. I did it purely for my kids, so my boys can laugh at their dad and have fun with it."
