Meryl Streep in Devil Wears Prada

Meryl's character Miranda is famous for her icy demeanor and control-freak antics.

While her character was criticized for not being as evil as the one in the novel, the fact remains that she was still at polar ends of what a Mary Poppins is.

Charlize Theron in Monster

After being the objection of affection of criminals, lawyer and giant apes, Charlize Theron probably thought it was time to drop dead some bipeds.

She plays the role of Aileen Wuornos, an abused prostitute who turns into a serial killer. It was good to see this pretty lass show off her acting chops.

Rebecca Romijn in X-men

Rebecca spent a large part of her career modeling for various magazines. Incidentally it was her first breakthrough role that was a negative one. She plays the comic book villain Mystique, a lady who chameleon-like powers.

Interestingly most of her body was painted on, thus she was required to be almost-n*de for the part.

Beyonce in Dreamgirls

In Dreamgirls, Beyonce's character got her bootilicious body to put her in the lead of her singing troupe.

Self seeking and ever-ready to hop onto the couch if it meant furthering her career, she embodies the amoral side of uncontrolled ambition.

Halle Berry in Catwoman/ Perfect Stranger

Halle Berry's experiments with the dark side have ended in complete disaster. Catwoman has been rated as one of the worst movies of all times. Perfect Stranger which also has her playing a crazy cat is unbearable. Be a nice girl and you won't be punished.
