Corey Alex Seaver (he/him) commenced acting in June 2017 as a recurring background high school student on the second season of the Netflix teen drama 13 Reasons Why (Anonymous Content). About halfway through production, his first film appearance arrived as a Pier 39 pedestrian in the 2018 Marvel Cinematic Universe entry Ant-Man and the Wasp.

Following this, opportunities began piling up and, upon completion of aforementioned series' third season, Seaver obtained speaking roles in student and independent films, as well as taking scene study courses at the Beverly Hills Playhouse. Among his repertoire includes The OA, Always Be My Maybe and A Taiwanese Tale of Two Cities (Netflix), Wheels of Fortune and A Christmas Mystery (ESX), Earth Mama (Park Pictures), Fremont (Blue Morning), I'm a Virgo (Media Res), Freaky Tales (eOne), The Lost Son Returns as the Duke (ReelShort), The Tutors (Galatea TV), and Artificial (Amazon/Heyday).

Whether it be an encyclopediac knowledge of the cinematic art or a devotion to the cult TV series Mystery Science Theater 3000 and its spiritual successor RiffTrax, Seaver is well versed in pop culture, has an enthusiasm for musical theatre, and watches a wide variety of film genres (he's very active on Letterboxd, under the username 'chief_mccloud'). He has penned short stories since junior high, and has only in the past few years advanced to screenplays. As of March 2026, he has become an avid fan of Twin Peaks (having watched episodes at his local Alamo Drafthouse), and attends various film events in his area.
