Katie Holmes and Channing Tatum play a happily married couple until drama enters their life in the thriller The Son of No One.

In the movie, which will be closing this year's Sundance Film Festiveal, Tatum plays a cop who uncovers a secret that could tear apart his family.

We love seeing Ms. Holmes, 32, play such a dramatic role. It's a far cry from her part in the upcoming Adam Sandler comedy Jack & Jill.

The Son of No One, also starring Al Pacino, premieres next Friday.
