Family Guy's Happy Hell-o-ween Dethrones Marvel on Disney+

The Devil Wears Kieran Culkin

The devil of Quahog's underworld wears a familiar face. Kieran Culkin, fresh off his Succession-era stardom, voices Satan himself in Family Guy's Happy Hell-o-ween, the standalone Halloween special that premiered on Hulu and Hulu on Disney+ on October 5, 2026. In the half-hour episode, Brian and Stewie make one of their worst decisions yet: they let someone drown because saving them would mean missing a Halloween masquerade cruise. A passing car sends both of them to Hell, where they have to answer for 24 seasons of bad behavior. According to CBR, the Devil in Happy Hell-o-ween ends up so exasperated by the pair that he hands them the keys to the underworld, which, knowing Brian and Stewie, is a transfer of power likely to end badly.

Culkin's casting was announced at this summer's San Diego Comic-Con by executive producer and showrunner Rich Appel, with Variety landing the scoop first, according to Dread Central. The pairing works because Culkin specializes in exhausted, put-upon authority figures, and Brian and Stewie are arguably the most annoying souls in existence. Absolute Geeks called the special among the show's most satisfying holiday outings in recent memory, praising Culkin's irritable Devil and the sharp meta-jokes about Disney+ passwords and obscure ABC TV movies.

The Streaming Upset Behind Happy Hell-o-ween

The numbers behind Happy Hell-o-ween are what turned a Halloween episode into a genuine story. FlixPatrol tracking cited by CBR showed the special becoming Disney+'s most-watched TV show, and the runner-up title overall on the service, behind Toy Story 5. The special displaced Coven Academy, a 21-part Freeform series launched as part of Disney's 31 Nights of Halloween push, which slid to third behind American Horror Story. A week later, according to Bubbleblabber, the special had seized the number one spot overall on Disney+ in the United States, ranking ahead of Avengers: Endgame at sixth and Avengers: Infinity War at seventh. A cartoon dog and a talking baby, in other words, beat the Avengers on Disney's own platform.

This did not come from nowhere. Family Guy premiered in January 1999, got canceled by Fox in 2002 after season three, and then did something television shows were not supposed to do: it came back. Reruns on Adult Swim starting in 2003 turned it into a late-night cult phenomenon, the show's debut DVD box set became the second-highest-selling television DVD ever, and Fox ordered new episodes. CBR notes the series has now aired more than 460 episodes across two dozen seasons, making it the 14th longest-running animated franchise in television history. Its survival is the original streaming-era comeback story, built on syndication and discs in an era before algorithms.

Adult Animation Is Having a Moment

The Happy Hell-o-ween surge fits a bigger pattern that Bubbleblabber flagged this week: adult animation is quietly pulling ahead of live-action blockbusters. Independent outfit Glitch Productions and Dana Terrace, creator of The Owl House, released a new episode of their sci-fi thriller Knights of Guinevere on YouTube, and it pulled nearly nine million views in its first 48 hours. Meanwhile, a National Research Group study commissioned by Crunchyroll, the Global State of Anime Fandom study, found that 82 percent of teen anime fans say anime makes up at least half of everything they watch. Bloomberg's reporting on the study put it plainly: teenagers are simply watching more animation than they did a year ago, and Gen Z is following them there.

Family Guy sits in the middle of that wave as the legacy act that refuses to age out. The Happy Hell-o-ween special even works as a commentary on the show's own longevity, roasting the characters' accumulated sins across the entire series. That self-awareness is the series' oldest trick: the show knows it has been around long enough to have a rap sheet, and it is happy to read the charges out loud.

The Peter Clause and Season 25

Happy Hell-o-ween is only the opening act of Disney's holiday plan for the show. A Christmas special titled The Peter Clause arrives later this fall, and the plot sounds exactly like Family Guy: Christmas comes to Quahog, Peter and the guys fight over who gets to be the town's official Santa, and Peter processes losing with all the maturity viewers would expect. Absolute Geeks reported that Season 25 returns to Fox in 2027, with episodes hitting Hulu the next day, and CBR noted the multi-season deal with Disney keeps the show on the air at least through the 2028-29 television season.

For a show that was literally canceled once, there is something poetic about outlasting the blockbuster machine on its own streaming home. Animated series have long been treated as the supporting act to live-action tentpoles, but the charts keep telling a different story. Glitch Productions does it on YouTube, anime does it across every platform, and now a 26-year-old cartoon from Quahog is doing it on Disney+. For viewers who grew up on Brian and Stewie's adventures, the lesson is a simple one: if you ever make it to the afterlife, do not let those two anywhere near the controls. Happy Hell-o-ween is currently available to watch on Disney+ and Hulu.
