Here Are The TV Shows And Movies You've Seen The Cast Of Hulu's "Reboot"

Bloom plays Hannah, the TV writer who pitches the reboot in the first place, as a way to seek a mix of revenge on and closure with her estranged father, the creator of the original series. She's best known for starring in and co-creating and co-writing Crazy Ex-Girlfriend, the musical TV series that ran on the CW.

You've probably also heard her in animated series like BoJack Horseman and Robot Chicken.

She'll be seen later this year in an as-yet-unknown role in Netflix's The School for Good and Evil.

Reiser plays Gordon, the aforementioned father and creator of Step Right Up. Depending on how long you've been alive and if you like watching older movies and TV shows, you might have seen him in Aliens, the Beverly Hills Cop franchise, and Mad About You. 

More recently, he appeared in The Kominsky Method, The Boys, and Stranger Things. 

Key plays Reed Sterling, one of the stars of Step Right Up, who's never quite managed to find the same level of fame he found through the show. 

There's honestly no telling where you might have seen Key before — he has over 120 credits to his name, including the upcoming Willy Wonka origin story Wonka. He co-created, co-wrote, and co-starred in the sketch comedy show Key and Peele alongside Jordan Peele and appeared on over 100 episodes of MADtv between 2004 and 2009. 

He's had guest roles in sitcoms like Parks and Recreation, Modern Family, and The League; lent his voice to animated series like BoJack Horseman, Archer, and Bob's Burgers; and starred in series and movies like Keanu, Schmigadoon!, and Friends from College.

Greer plays Brie Marie Jensen, another Step Right Up star who signed up for the reboot after her marriage fell apart.

Like Key, Greer has been in a lot of movies and TV shows. One of her first roles was as the iconic Fern Mayo/Vylette in Jawbreaker, and since then, she's appeared in rom-coms like The Wedding Planner, 13 Going on 30, and 27 Dresses; horror movies like Cursed, Carrie, and the latest Halloween reboot. 

You might also recognize her as Kitty Sanchez in Arrested Development or Bridget in Two and a Half Men. 

Knoxville plays Clay Barber, a comedian who costarred in Step Right Up, was later arrested, and spends a lot of time teetering on the brink of being canceled.

You likely recognized Knoxville from Jackass, but you might have also seen him in the mid-2000s comedies The Ringer, The Dukes of Hazzard, and A Dirty Shame, or on a few episodes of Drunk History (as Johnny Cash, among others). He also appeared in a few more serious movies, like Walking Tall and Lords of Dogtown.

Worthy plays Zack, the youngest member of the Step Right Up cast, who despite being in his mid-20s is still more or less trapped in child star-mode.

Worthy's a pretty great choice for the role, as a former kid actor himself. He landed his first onscreen role when he was 9, and has since starred in Austin & Ally, American Vandal, and The Act. He's also had guest roles on Supernatural, Smallville, and Good Luck Charlie.

Yu plays Elaine, the "new to humor" Vice President of Comedy at Hulu. If she looks familiar, you've probably seen her on Dr. Ken or on Last Man Standing. She's also appeared on Cougar Town, Switched at Birth, and Agent Carter.
