Arnold Schwarzenegger - Arnold Schwarzenegger Explodes Movie Myth About Gerard Butler's 300 Physique

Schwarzenegger made the discovery after approaching the film's producer Mark Canton and asking for details about the fitness regimen Butler adopted to look like a beefy warrior.

The impressed Terminator star wanted to track down the Scot's trainer and hire him to get him back into blockbuster shape, following his two terms as California Governor - and was shocked to discover Butler's look was all movie magic.

He tells Entertainment Weekly magazine, "I said to Mark Canton, 'You have got to get a hold of this guy (Butler). I want to know what his training regimen is.'

"Canton said, 'What are you talking about? (That look) cost me a lot of money.'"
