Jessica Alba reportedly walked out yesterday during the Sundance Film Festival’s screening of her serial-killer drama The Killer Inside Me. Alba plays a prostitute-turned-punching-bag in director Michael Winterbottom’s adaptation of Jim Thompson’s 1952 novel of the same name.

Why Alba left is unknown but, according to critics in attendance, there were quite a few walkouts from folks who found the film’s violence towards women disturbing, namely scenes featuring Alba repeatedly punched in the face and taking a ruthless belt-lashing across her ass from Casey Affleck, who plays Texas lawman and sociopath Lou Ford.

The flick also includes some nasty rough sex between Affleck and Kate Hudson, who gets choked during a scene that would give David Carradine a boner … if he weren’t a perverted dead bastard right now.

Jessica Alba was chosen by Clatto as one of the Ten Hottest Horror/Sci-fi Babes of the Past Decade.
