Britney Spears' ex-husband KEVIN FEDERLINE is embarking on a movie career after landing a part in Keanu Reeves' new film. The dancer/rapper will play a "small but notable" role in the thriller Night Watch, opposite Reeves and Oscar winner Forest Whitaker, according to In Touch Weekly magazine. It won't be the 29-year-old's first acting job - he appeared in an episode of TV drama CSI: Crime Scene Investigation, which aired in America last year (06).
