One Degree: Greg Grunberg and Masi Oka

Sorry to be a little late. The answer to last week's One Degree was Empire of the Sun. Ben Stiller appeared as an extra, while Christian Bale, then a child actor, starred in his first lead role. I would have had no idea that Ben Stiller was in that film, except that he said he thought of his idea for his new movie Tropic Thunder, while working on Empire of the Sun.

If you like Heroes, you know Greg Grunberg as psychic policeman Matt Parkman and Masi Oka as time-traveling Hiro Nakamura.

What movie did Grunberg and Oka appear in together?
