Cameron Crowe’s in-the-works Showtime pilot Roadies just added another cast member. THR reports that Mad Men’s Christina Hendricks has signed on to play production manager Shelli, described as “tough but privately emotional, married to her job and scary good at it.†Hendricks joins previously announced cast members Luke Wilson, Imogen Poots, Keisha Castle-Hughes, Peter Cambor, and Rafe Spall. Roadies makes the second TV comedy project involving Hendricks in recent months following October’s news that she had joined the cast of Natasha Leggero and Riki Lindhome’s upcoming Comedy Central series Another Period.
