15. CAMERON DIAZ

Movie: Being John Malkovich (1999)
After There’s Something About Mary was released in 1998, Diaz took on a role that was significantly less attractive to secret admirers and stalkers. In the cult-classic, Diaz paired an unmanageable 80s-esque wig with a number of crazy cat lady like outfits to play the outlandish Lotte Schwartz.
