Saturday Night Live premiered 49 years ago on Oct. 11, 1975. With biopic Saturday Night now playing in theaters, it is the perfect time to revisit the show's first-ever episode.

Set in the 90 minutes leading up to SNL's first broadcast, Saturday Night peeks behind the curtain at the chaos of putting a countercultural live comedy show on the air for the first time. The film ends just as the show finally begins, which renewed our curiosity to revisit the actual first episode of the variety series.

NBC

Fortunately for comedy fans, all 50 seasons of Saturday Night Live are currently streaming on Peacock. That means you can watch the very first episode of SNL, which features host George Carlin and musical guests Billy Preston and Janis Ian, by scrolling back to the very beginning of the show's catalog on the streamer.

The first ep of the show introduced the world to cast members who have now become comedy legends: Chevy Chase anchors the first-ever "Weekend Update" segment with special correspondence from Laraine Newman; John Belushi gets a morbid English lesson from head writer Michael O'Donaghue; Dan Aykroyd tests the limits of Gilda Radner's home security; and Garrett Morris assists Jane Curtin in court as she writes down her disturbing testimony instead of speaking it aloud.

The show hadn't solidified its now-predictable structure at the time of the premiere, so the episode features a number of deviations from the contemporary SNL formula that might surprise modern viewers. For example, Carlin has four different standup segments rather than the now-standard singular monologue (and doesn't appear in any sketches), and there are a total of four musical performances, two each from Ian and Preston.

The episode also features a number of segments supplied by comedians and entertainers who weren't part of SNL's cast. Legendary comic Andy Kaufman does a brief lip-sync routine to the Mighty Mouse theme, Albert Brooks provides a short film about bizarre news stories, Valri Bromfield does her own short standup routine, and Jim Henson sends the Muppets into the Land of Gorch for the first time.

Saturday Night stars Gabriel LaBelle as SNL creator Lorne Michaels, Rachel Sennott as writer Rosie Shuster, Lamorne Morris as Garrett Morris, Cory Michael Smith as Chevy Chase, Dylan O'Brien as Dan Aykroyd, Ella Hunt as Gilda Radner, Kim Matula as Jane Curtin, Matt Wood as John Belushi, Emily Fairn as Laraine Newman, Tommy Dewey as Michael O'Donaghue, Cooper Hoffman as NBC exec Dick Ebersol, Willem Dafoe as NBC head of talent David Tabet, J.K. Simmons as Milton Berle, and many, many, many more.
