Why did Matthew Vaughn leave X-Men: Days of Future Past? Turns out, rumors that he wanted to concentrate on The Secret Service were right on the money, according to co-creator (and executive producer of the movie) Mark Millar:
We thought Matthew was going to do X-Men first, but we found out there were actually a few imitators of ‘Secret Service’ in the works. People think you’re lying when you say you’re not trying to get your comics made into movies so quickly, but the two reasons it happens like that is first because it’s the best ad for the comic you’ll ever have. And for me, selling the book is the most important thing. The second reason is because people are always trying to rip you off. Somebody will start to work on a spec screenplay about your idea. There are three other projects I know of now about a James Bond kind of guy taking a street kid and turning him into a spy. Three screenplays were already going through Hollywood about this! So Matthew and I said, ‘Fuck this. We’re not letting anyone steal our ideas.’
So, I wonder how quickly we’ll see a Secret Service movie in theaters, if they’re planning on making this as soon as possible…?
