A screening of Inception this past weekend turned into a reeeeeeeaaaaalllllll nightmare for Matthew Vaughn (crickets). Vaughn says that he was sunk when he saw Joseph Gordon-Levitt involved in a zero gravity fistfight because it was too similar to what they were planning to do with X-Men: First Class. The scene in question would feature James McAvoy’s Professor X in "dream-space combat" with "spinning rooms and other physics-bending imagery," but now it’s been torn from the script as Vaughn’s team brainstorms a new set piece. "So it’s either leave it in and look as if you’re copying or change things. We completely ripped out about 12 pages of the script and the storyboards," commented Vaughn.
