Actress Rhona Mitra is definitely no stranger to the ways of the law. She spent a good deal of time on The Practice, and then jumped ship for the ultra-wacky law show Boston Legal. Since then, well, she's not only got nipped and tucked, but she's taken some time for Skinwalkers, the flop that is The Number 23, and Shooter. Now The Hollywood Reporter has posted that she's going to co-star in a new indie thriller called The Boy in the Box -- written by actor Glenn Taranto and helmed by Anders Anderson.

No, this is not a retro celebrity biopic about Corey Hart. Rather, it's about a "small-town police chief (Jon Hamm, We Were Soldiers ) determined to discover the truth behind the mummified remains of a boy who was murdered a half-century earlier." Mummification -- that's not something that pops up in a thriller every day. Or in life for that matter. Anyway, Mitra will play "the police chief's wife, who is trying to move on after the disappearance of their own son eight years earlier." No wonder he's obsessed.

But there's even more cast on this sucker. The film is re-teaming Mitra with Sweet Home Alabama co-star Josh Lucas, who will play the slain child's dad. I imagine that means flashbacks -- since Lucas sure as hell isn't old enough to have a son who has been dead for 50 years. Wrapping things up, there's Dawson Leary / James Van Der Beek, Marcus Thomas (You Kill Me), the young tyke Jimmy Bennett (Evan Almighty) -- who I imagine will play the slain kid, and Jessica Chastain (Law and Order). I'll just go out on a limb and say Dawson did it! He's got a good creepy look to him when he wants to. As for you Buffy and Grey's fans out there, Box also has the vengeance demon/overachieving doctor Kali Rocha.

It'll be a little while before this film gets up and running. Having tackled the skinwalkers, Mitra is about to head for New Zealand and face lycans in Underworld: Rise of the Lycans.
