Cameron Diaz – Being John Malkovich

Bubbly, blonde Cameron Diaz underwent quite a transformation for her role as Lotte, the wife of John Cusack's character in Being John Malkovich. Make-up artist Gucci Westman is credited with the look, which included a frizzy hairdo, brown contacts and a frumpy appearance. Cameron's transformation was so amazing that when she was dressed in character and talked to some of the crew on the set, they had no idea who she was. Cameron received a Golden Globe nomination for her work in the movie.
