Mad Men alum Kevin Rahm is set as a series regular opposite Damon Wayans Sr. in Lethal WeaponFox’s hourlong pilot based on the hit buddy cop action comedy movie franchise.

In the pilot, written by Matt Miller and directed by McG, when Texas cop and former Navy SEAL Martin Riggs suffers the loss of his wife and baby, he moves to Los Angeles to start anew. There, he is partnered with LAPD detective Roger Murtaugh (Wayans), who, having recently suffered a “minor” heart attack, must avoid stress in his life.

Rahm will play the successful yet humble Captain Avery, more politician than cop, dressing the part of top brass since his early days as Murtaugh’s partner. Avery, who paired up Murtaugh with Riggs, hoping the younger cop can put a little vigor back in Murtaugh’s career, enjoys the corner office that came with his recent promotion to Captain.

Miller, McG, Dan Lin and Jennifer Gwartz executive produce the pilot for Warner Bros. TV and Lin Pictures.

Rahm, who played Ted Chaough on Mad Men for four seasons, rising to regular in Seasons 6 and 7, recently recurred on CBS’ Madam Secretary. The Desperate Housewives alum is repped by Gersh and Forward Entertainment.
