Milo Ventimiglia (Heroes) has signed on for Frank Darabont's upcoming period crime drama LA Noire.

The pilot episode will be written and directed by Darabont with the plan being that the show will become a regular series on TNT. Here is the synopsis of the show:

"L.A. Noir is the true story of a decades-long conflict between the Los Angeles Police Department, under the determined leadership of Police Chief William Parker, and ruthless criminal elements led by Mickey Cohen, a one-time boxer who rose to the top of L.A.'s criminal world. The series is a fast-paced crime drama set in Los Angeles during the 1940s and '50s. It's a world of glamorous movie stars, powerful studio heads, returning war heroes, a powerful and corrupt police force and an even more dangerous criminal network determined to make L.A. its West Coast base."
