Nicholas Hoult was the adorably weird Marcus Brewer in About A Boy, also starring Hugh Grant and Toni Colette. After a successful move into American film (like X-Men: First Class), Hoult starred in the 2013 movie Warm Bodies, a Romeo-and-Juliet-esque story of love, loss and difficult circumstances… Like “I ate you boyfriend’s brains and now I love you,” kind of difficult.
