Nevermind that John Krasinski doesn’t look old enough to have a teenaged daughter. The trailer for Lena Dunham’s latest movie Nobody Walks has "I’m seeing this" written all over it.

Nobody Walks, co-written by Dunham and director Ry Russo-Young, stars Krasinski as a married sound editor who invites Olivia Thirlby to stay in his guest house while he assists her with a project. Romantic little sound-related overtures to each other are made and wife Rosemarie DeWitt is getting jealous. But she’s got a clandestine relationship of her own: a therapy patient who has the hots for her.

It’s the kind of movie where characters say things like "Marriage is complicated!" … but that won’t stop me from seeing it. Both Rosemarie DeWitt and Olivia Thirlby deserve to be much more famous than they are and the Nobody Walks trailer just adds more evidence to that theory.

Plus, it’s a bit of a darker turn for Lena Dunham, writing-wise. Oh, and did I mention Dylan McDermott is in it?
