Geoffrey Arend is best known for his quirky roles in Body of Proof and (500) Days of Summer (as well as his real-life role as husband to Christina Hendricks), but in the Sundance romantic comedy Save the Date, he plays a bellowing indie-rock star so convincingly that you want to go on iTunes and download his songs immediately after screening the movie. When we caught up with Arend last night at Chefdance, he confessed that he’s working on his own eighties-music-inspired project called Star Hold, but he’s had plenty of practice at playing rock star — in fact, for a friend’s musical covers party two years ago, “I did Hedwig and the Angry Inch in full getup,” said Arend. “My wife would come home and I’d be walking around in white platform boots, just practicing, because I knew if I tried to rock out I’d just break my ankles because I’d never walked in platform boots before. So she’d come home and I’m dressed regularly for two thirds of my body and then I’ve got on these white platform boots, and she’s like, ‘I gotta go to bed.'” But Hendricks, too, has had to wear some perilous shoes for Mad Men! “I know, but you never expect your husband to walk around like a drag queen, you know what I mean?” laughed Arend.
