The Mentalist is joining THE KILLER INSIDE ME.

Simon Baker (The Mentalist) has signed on for the upcoming film of Jim Thompson’s The Killer Inside Me, according to THR.

Baker will be playing a county attorney that realizes the monster that the sheriff (Casy Affleck) has become, and works to expose him.

In addition to Baker and Affleck, Kate Husdon and Jessica Alba are on board.

I have to say I am really curious about this. I have seen some of The Mentalist and while the show is so-so, Baker is quite enjoyable. Casey certainly is developing a repuation as a dramatic actor. He was not the Patrick Kenzie I envisioned, but I thgouht he did a very good job in Gone Baby Gone.
