James Marsden will play Cam and Mitch’s shirtless neighbor on ABC’s sitcom Modern Family. Dane DeHaan will play a troubled gay teen on HBO’s shrink series In Treatment. And Showtime’s new odd-ball family dramedy Shameless (see above trailer, starring William H. Macy and Emmy Rossum) will have Cameron Monaghan playing a teenager who gets involved with a married older man (whom he works for?). That one premieres Jan. 9. We’ll be watching.
