Waystar Studios is a movie production studio responsible for the Thanksgiving-themed box office bomb The Biggest Turkey in the World, a franchise of movies called Frat Baby (perhaps a riff on Boss Baby ), Kalispitron (a disastrous production responsible for losing Waystar large chunks of change), and an animated film called Morons (likely a reference to Minions ). Waystar Studios is based in Burbank, California and run by Joy Palmer ( Annabeth Gish ), at least until Roman Roy ( Kieran Culkin ) impulsively fires her. Fun fact: the Waystar Studios scenes in Season 4, Episode 6 were filmed at the actual lot and offices of Warner Bros. Studio. (Warner Bros. Discovery is the parent company of HBO.)
