Jessica Alba takes a comedic turn in her 'Good Luck Chuck'

In her latest movie, Jessica Alba falls into a penguin pond, stabs Dane Cook with a dental tool and accidentally tears off her skirt by closing it in a car door.

The 26-year-old actress plays Cam, a clumsy penguin-keeper who captures Cook's heart in "Good Luck Chuck," in theaters Friday.

The role represents a departure for Alba, who gained fame as an action star - first on TV's "Dark Angel," then in films such as "Fantastic Four" and "Sin City."
