Nicholas Hoult has confessed he is not a natural when it comes to playing the action hero.
The 23-year-old star of Skins and About A Boy has landed his first leading role in a feature film, as Jack in Jack The Giant Slayer, Bryan Singer's film adaptation of the classic fairytale.
Nicholas revealed: "I did some climbing practice but my character's not supposed to be a great climber and he's scared of heights, so I didn't have to look like an action hero.
He also learned to ride a horse, but wasn't what you'd call a natural in the saddle.
"Not at all," he confessed. "And it was painful, but then the wardrobe lady got me a pair of jodhpurs to wear underneath my costume."
Nicholas appeared alongside Colin Firth and Matthew Goode in Tom Ford's directorial debut A Single Man, and was part of the ensemble cast of X-Men: First Class. But he admits he is feeling a little nervous about being the leading man for the first time.
"It's stressful," he said. "Luckily as an actor you're not holding the whole production together, but I feel the pressure definitely because you've still got to try and put in a performance that's maintained to the high level."
