LOS ANGELES: Desperate Housewives’ Eva Longoria takes on her first major movie role in The Sentinel. Playing a Secret Service agent opposite Michael Douglas and Kiefer Sutherland, Longoria ditches her designer dresses and flirty attitude in favour of smart suits and a serious demeanor. “I wanted to venture out of Gabrielle as soon as I could. That was my motivation, to make sure I broke out fast enough.”
