Joss Whedon
Parts of the storyline in the movie X-Men: The Last Stand are very similar to what he wrote in the Marvel comic book Astonishing X-Men. The idea of a cure for mutation was his story. The scientist who finds the cure in the movie is named Dr. Kavita Rao. This is the same name as the scientist in the comic book. Simon Kinberg has said someone at the studio who had read Whedon's comics asked the writers to use a mutant cure idea in their script.
