Logan Marshall-Green is among three additions to 'The Line'

TNT's Jerry Bruckheimer-produced pilot about undercover cops has signed three actors for its cast, including former "Traveler" star Logan Marshall-Green.

Marshall-Green will star in "The Line" with Nicki Aycox ("Supernatural") and Omari Hardwick ("Miracle at St. Anna"). Another TNT pilot, "Bunker Hill," has added Tony Curran to its cast, according to The Hollywood Reporter.

"The Line" follows a group of young undercover officers in Los Angeles who have to avoid the temptations of the underworld in order to do their jobs. The show comes from "Big Love" writer Doug Jung and the "CSI" team of director Danny Cannon and producers Bruckheimer and Jonathan Littman.

Marshall-Green's credits also include "The O.C." and "Across the Universe." Aycox has appeared on "Ed" and FX's "Over There," while Hardwick co-starred in TNT's "Saved" and "The Guardian."

"Bunker Hill" stars Donnie Wahlberg as a war veteran who becomes a Boston cop and finds himself working the streets of his old neighborhood. The show comes from "Law & Order" veteran Walon Green and director Jon Avnet ("The Starter Wife," "88 Minutes").

Curran, whose credits include "Miami Vice" and "The League of Extraordinary Gentlemen," will play a homicide detective and colleague of Wahlberg's character.
