Interesting fact:

Kirsten Dunst, a natural blonde, wore a red wig in the first ‘Spider-Man’ film to play Mary Jane. However, she felt that her red glow actually attracted a different kind of man in the real world, so she dyed her hair red for the second film. Her quote on the matter: “I attract a different kind of boy when my hair’s red. I get more quality men—like a more thoughtful, nerdy dude.”
