Casting for HBO's upcoming TV adaptation of Jonathan Franzen's The Corrections is well underway: Dianne Weist and Chris Cooper are on board to play the central Lambert parents, and now, Deadline is reporting that Ewan McGregor has signed on for his first regular TV gig to play middle child Chip. We no longer care who gets cast as the other two Lambert children—the only question now is, will we get to see McGregor's junk?

It certainly wouldn't be the first time—McGregor has a long history of taking it all off on camera (see: Trainspotting, The Pillow Book, Velvet Goldmine, Young Adam), and, despite his insistance that it won't happen again, the role of Chip seems prime for showing a little skin. Case in point: early on in the book, we learn that Chip has been fired from his cushy academic position at an elite college for sleeping with a student—sexy! Here's hoping that director Noah Baumbach can coax one last nude scene out of the old pro.
