Alec Baldwin is heading back to TV to appear in Mariska Hargitay's directorial debut as she takes over the reins of her hit crime drama Law & Order: Special Victims Unit. The actor has been away from the small screen since last year (13) after his sitcom 30 Rock finished and his political TV talk show was cancelled. However, he will now make a return to acting after landing a role in the long-running Law & Order spin-off. The episode featuring Baldwin will also mark the directorial debut of the show's star Hargitay, who will be fulfilling an ambition by taking charge of the drama. She says, "It's a long time coming; I've wanted to do it for a while. There are a lot of things that I've learned and collected... I'm up for the challenge... It feels like a natural progression." Baldwin adds in a post on Twitter.com, "The week of Feb 24, I start shooting Law And Order SVU. The director is the one and only... (Mariska Hargitay)." The episode is due to air in the U.S. in the spring (14).
