I was brought on as they were casting, so I was lucky enough to be there for some of the people who came in like Terence Stamp for Xavier and Janet Jackson and Mariah Carey for Storm. Michael Jackson came in because he wanted to play Professor X. It was amazing. Shaq came in. Viggo Mortensen came in. I really liked Viggo for Wolverine, but it didn't come together for whatever reason. Angela Bassett was our first choice for Storm, but her agents wanted more money than we had at the time. Same with Rachael Leigh Cook for Rogue.
