Cannon is getting himself in fighting shape for the film, which is currently titled THE HAWK.
He says, 'It's a father-and-son story that I wrote. I'm still training, but I don't start filming till next year.
"I always liked boxing. I got into boxing because Will was doing Ali, and I was hanging out on the set with him. I got with the boxing trainer who trained Will for that, and we just kind of came up with the idea."
