'Jack' Cast Evaluates Rising Star Nicholas Hoult

After capturing Hollywood's attention as a teenager with his performance in About a Boy, Nicholas Hoult is on the rise, starring in two films released in consecutive months. At the Los Angeles premiere of Jack the Giant Slayer, in which he plays the title character, Hoult's co-stars revealed their experience working with him for the fantasy film.

"Oh, he's a nightmare," joked Eleanor Tomlinson, who plays a princess in the film. "No, he's not really. He's lovely. He's a gentleman to work with. He's a fantastic actor as well so he gives you a lot to work with, which is great."

In addition to her flattering comments for her co-star, Tomlinson, who officially made her American film debut at age 14 in the period drama The Illusionist, declared herself the luckiest girl in the world to have starred in the film and make her first trip to Los Angeles for the red-carpet premiere.

Jack director Bryan Singer, who previously worked with Hoult as a producer on X-Men: First Class, spoke on what makes Hoult a successful screen actor.

"He's great. He's incredibly charismatic, but he's also extremely vulnerable, so I think the audience roots for him," said Singer, who has directed a handful of the recent X-Men films. "They want him to succeed; they want him to have adventure, get the girl. All that stuff."

Jack the Giant Slayer will premiere in wide-release this Friday, exactly a month after another film in which he starred, the paranormal romantic comedy Warm Bodies, made its premiere.

As Warm Bodies continues to cash in at the box office, Hoult has another few starring roles lined up, including a reprisal of his X-Men role for the seventh installment in the franchise, Days of Future Past. The English actor said he's enjoying his ascension in Hollywood.

"It's been great. I was very relieved that 'Warm Bodies' did well and people liked it," the 23-year-old actor said. "I hope that people enjoy this [film] as well. We had a lot of fun making the film. I'm having a good time; I'm enjoying it."
