Out of the entire fifth season of Mad Men this past year, some of the key highlights belong to John Slattery and his character of Roger Sterling. Between a heated battle with Pete Campbell to taking an LSD trip with then-wife Jane, he was certainly at the point of plenty dramatic twists and turns while also allowing us to laugh among the heavier developments. With a personality and sharp wit, Slattery certainly knows how to play his character well and has demonstrated this same style with other roles in television and film. Now, it seems he’s ready to supply some comedy to one of the most high-profile returns for a television series ever: Arrested Development.

TV Line reports that Slattery has joined the fourth season ofArrested Development in an undisclosed recurring role that will have him popping up in multiple installments of the 10 episode run.

Many have begun to speculate just who he may be playing, such as a Never-Nude, a distant Bluth relative, or someone connected to the more business side of things, but a rep for the series declined to comment.

This casting comes after narrator and executive producer Ron Howard revealed that this fourth season would bring a slew of new characters while also exploring the characters since they’ve been away. Slattery joins previously confirmed guest stars Anders Holm, Adam DeVine and Blake Anderson fromWorkaholics, who were seen to be playing a guest spot in an airport scene the first episode back.

This won’t be Slattery’s first comedic gig. The actor has played parts in 30 Rock, The Cleveland Show, Sex and the City, and even Ed. He’s also played prominent roles in Iron Man 2, The Adjustment Bureau and the short lived WB series Jack & Bobby.

Arrested Development‘s fourth season will premiere at an undetermined time in 2013 on Netflix, with all 10 new episodes appearing on the service on the same day.
