Simon Baker (from CBS's The Mentalist) will star opposite Casey Affleck in The Killer Inside Me, playing an attorney on the trail of a murderer in Michael Winterbottom's adaptation of the Jim Thompson noir classic.

According to The Hollywood Reporter, the story centers on a West Texas sheriff (Affleck) and his downward spiral from a boring small-town cop into a ruthless, sociopathic murderer. The cast also includes Jessica Alba as a prostitute and Kate Hudson as the sheriff's schoolteacher girlfriend.

Baker plays a county attorney looking to expose the sheriff as the killer.

Filming begins this week in New Mexico and Oklahoma.
