Actor Luke Evans struggled on the set of his breakthrough movie Clash Of The Titans because he didn't understand the jargon used by film industry insiders. After spending the first decade of his career on the London stage in productions such as Rent and Miss Saigon, the Welsh hunk landed his first major big screen role playing Greek god Apollo in the 2010 fantasy blockbuster. However, Evans felt out of his depth as soon as the cameras started rolling because he had no previous experience of working on a movie shoot. He tells Men's Health magazine, "It was the scariest thing I've ever done. I had no knowledge. All the jargon they use on set - I had no clue. And the first day on Clash of the Titans, I was working with Liam Neeson... I'm thinking, 'OK, just act. Just do what you know you can do.' And it just picked up from there. It is a constant learning curve."
