Glamorous actress Eva Longoria wants to let herself go and show her dirty side in a gritty, dark film drama. The Desperate Housewives beauty, 30, was inspired by Halle Berry's Oscar-winning turn in MONSTER'S BALL and believes challenging roles are the key to winning awards. Longoria says, "(I want to do a ) Monster's Ball-type thing like Halle Berry. I think you can stay sexy and still do really challenging roles."
