Lean, mean and back on the screen
According to MTV the muscle bound star, who played The Hulk in the original TV series as well as a number of movie spin offs, will be making a brief appearance in the characters latest celluloid outing, The Incredible Hulk.
Mr Ferrigno, who was also a one time Mr Universe and has competed against legendary body builders such as Arnold Schwarzenegger, told MTV that the movie was looking "impressive" and that his replacement, Edward Norton, was doing a great job.
"I believe he rewrote the script because he's very involved with the character," he said.
He added: "He's not just doing another movie, he wanted to be involved with the character. I think that's going to bring it to the next level."
Earlier this month, SuperHeroHype.com reported that Leterrier had said that a recent leaked script for The Incredible Hulk was "6 months old and a lot has changed...for the better."
As well as Edward Norton as Hulk and his alter ego Bruce Banner, the movie stars Liv Tyler as Betty Ross and Tim Roth as arch-nemesis Abomination.
