Luke Evans has admitted it was terrifying making the transition from stage to screen.
The Hobbit actor has plenty of theatre experience under his belt, but didn't get his big break in Hollywood until he was cast in 2010's Clash Of The Titans remake, and confessed it was a steep learning curve, reported E! News.
He told 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."
Luke, 34, went on to land parts in films such as The Raven, Fast And Furious 6 and then The Hobbit movies.
The actor also revealed fans are unlikely to see him becoming a big presence on social media.
"For your own self-respect and sanity, your creative freedom, you have to be careful that you don't rely too much on other people's opinions of what you do, because it can stunt and inhibit you," he said.
"You can read 50 great things about yourself, but the one bad thing will be what you remember most."
