24. Jessica Biel as Erin Hardesty, The Texas Chainsaw Massacre (2003)
It's not like Erin Hardesty (played by Jessica Biel and her front-and-center cleavage) needed to do anything more than simply walk around. Thanks to shameless director Marcus Nispel, the 2003 remake of The Texas Chainsaw Massacre very proudly flaunts its greatest asset, with numerous shots of Biel's twos taking up most of the camera's space.
So it's a nice bonus that Erin is also the kind of sexy tomboy who's unafraid to fight back against Leatherface (by lopping his arm off with a machete) and the chainsaw-wielding ogre's elder colleague, corrupt Sheriff Hoyt (by running him over with a cop car).
