"I started too late. It probably wasn't my thing. I should have done a different sport."
Statham, who was joined on the red carpet by his supermodel fiancee Rosie Huntington-Whitely, said he got "fulfilment" from his leading roles in action films.
Starring opposite actress Jessica Alba, he plays assassin Arthur Bishop in Mechanic; Resurrection - a sequel to the 2011 remake of the Michael Winner film The Mechanic.
Statham said: "I think I'm more suited to action movies than courtroom dramas so I tend to stick to those.
"It's something I get a lot of fulfilment out of. I feel I'm better at those than I am at other stuff. I play to my strength I suppose."
Mechanic: Resurrection director Dennis Gansel said he believed Statham was "the best" action movie star working in Hollywood.
"I've been a fan of him since day one in Guy Ritchie movies," he said.
"He turned himself into this action star. I think he's the most diverse and interesting guy working in the industry today.
"If he wouldn't be an A-list star, he would be one of the best stuntman working out there."
