SuperHeroHype: When you were in New York six years ago for "Layer Cake," you were already well into development on the third "X-Men" movie and you had a lot of great ideas that sounded cool, then you left that. And now you're back, so what was the biggest factor in convincing you to do another movie? Was it the story or Bryan Singer's involvement?
Matthew Vaughn: Unfinished business, that's what inspired me. I was totally excited about doing "X3" and basically co-wrote the script with (Simon) Kinberg and Zak Penn. We did that in six days together, and then storyboarded the whole movie, prevised all the big sequences, and then like an idiot, thought that I didn't have enough time to make the film I wanted, so I had to leave. I sort of regretted that ever since, and when Fox rang me up and said, "Do you want a chance to reboot X-Men and put your stamp all over it?" When they told me that, I thought they were joking at first, and then they told me it would happen in the '60s against the Cuban missile crisis as the backdrop, I thought, "God, this sounds cool. Why not? Let's do it."
