X-Men (2000)

Trivia: Patrick Stewart has said preparing for the role of Xavier was the most fun he's ever had preparing for a role, because the studio was constantly sending him comic books to read.

Trivia: While they look great on-screen, reportedly the leather costumes the cast wore were a massive pain behind the scenes. They were so stiff at the start of the shoot, the cast could barely move in them. The first day of shooting, the cast was supposed to hop over a small ledge, and none of them could do it because the suits weren't flexible enough. Thankfully, the suits eventually began to loosen up the more the cast wore them.

Trivia: Hugh Jackman would start getting into character by taking ice-cold showers every morning the instant he woke up. They put him into an angry mood that he would then use for the character. He reportedly continued the tradition with every sequel.

Trivia: The studio was hesitant about the film and didn't want to take a big financial risk on it. Thus, they reduced the budget to $75 million in comparison to the $90-$100 million many other blockbusters at the time cost.

Trivia: Alicia Silverstone, Drew Barrymore, Sarah Michelle Gellar, Jennifer Love Hewitt, and Christina Ricci were all considered for the part of Rogue.

Trivia: Russell Crowe, Dougray Scott, Keanu Reeves, Mel Gibson, Jean Claude Van Damme, Edward Norton, Gary Sinise, Aaron Eckhart and Viggo Mortensen were all considered for Wolverine.
