Kellan Lutz - Kellan Lutz couldn't get as 'big' as Dwayne Johnson for Hercules
Kellan Lutz has joked he had no chance of matching Dwayne Johnson's physique while the two actors play Hercules in separate films based on the Greek hero.
The two actors play the Greek hero in separate movies, and the 'Hercules: The Legend Begins' star joked his body could never match up to The Rock's.
He told E! News: ''I wanted to get big, but then you have The Rock playing in the other Hercules. There's not enough 'extra-curricular' stuff for that.''
The 28-year-old star has still put himself through a tough and ''rigorous'' training regime to getting into top shape for the film.
He added: ''I wanted to put on weight. Renny [Harlin] the director, he just wanted me cut, so I had to get cut ... For me, it was very rigorous training.
''I had to learn how to ride a horse while wielding a sword and fighting mercenaries, as well as giving a badass speech and in the rain. And horses don't like the rain. It was very rigorous.''
Kellan also revealed while he can't match the 'Hercules: The Thracian Wars' star in terms of his physique, he's been glad to let himself indulge in some sweet treats on set.
He said: ''If you've ever been on a movie set, there's food all the time. It's hard to stay healthy because I had milk chocolate bars three times a day, and I'd just eat the whole bar.''
