Domhnall Gleeson in Crash Pad (2017)

Domhnall Gleeson got naked for the comedy Crash Pad. Domhnall plays Stensland, a romantic slacker who thinks he's found true love, only for his lady love to reveal that he's been a tool for her to get revenge on her neglectful husband. She reveals the truth in the opening scene, leading Stensland to pace around upset while naked. Domhnall gets a second rear nude scene later in the film when he wakes up in the hallway of his apartment building wearing only a shirt. Of course, he finds himself locked out just in time to be seen.
