13 Famous Comedians in Trainwreck — Besides Amy Schumer

Let's start with the obvious: Hader, who you probably recognize from Saturday Night Live, plays Amy's love interest, Aaron. He's also starred in movies like Superbad, Adventureland, and The Skeleton Twins, in addition to playing the recurring role of Tom on The Mindy Project.

Veteran comedian Quinn, who has guest starred on two episodes of Inside Amy Schumer, plays Amy's father in Trainwreck. Quinn had a long run as SNL's Weekend Update anchor and has popped up in a number of movies starring SNL cast members, including A Night at the Roxbury, Grown Ups, and That's My Boy.

If Amy's brother-in-law looks familiar, it's because he's played by Mike Birbiglia. He's famous for his stand-up sets, one of which he turned into a movie called Sleepwalk With Me. Birbiglia has also appeared in The Fault in Our Stars, Hot Pursuit, and an episode of Girls.

Well-known comedian Attell appears in Trainwreck as a homeless man outside Amy's building — yeah, that's him! He's been a staple on the comedy scene since the '80s, writing for SNL and The Jon Stewart Show before creating his own projects like Insomniac With Dave Attell and Dave's Old Porn.

Amy's workplace is teeming with comedians. Jon Glaser (Parks and Recreation, Girls), Randall Park (The Interview, Fresh Off the Boat), and Vanessa Bayer play her colleagues. You definitely know Bayer from SNL, which she's been on since 2010.

Those two girls next to Amy on the couch in the awkward party scene are Nikki Glaser and Australian stand-up comedian Claudia O'Doherty. Glaser has been on several episodes of Inside Amy Schumer, and both are recognizable names in comedy. The woman who takes the game way too far is Everett, a friend of Schumer's in real life, who has appeared on Inside Amy Schumer a few times. In case you watched the episode of The Bachelorette in which Schumer guest starred, Glaser and Everett also appeared!
