Family Guy Halloween specials have consistently delivered some of the animated series' most memorable episodes, with entries such as Halloween on Spooner Street leaning into the show's trademark chaos and seasonal humor. These annual spooky stories give the series room to explore supernatural plots, celebrity cameos and darker comedy outside its usual Quahog adventures.

This year's Halloween special pushes that tradition into Hell itself, with an unexpected star stepping into one of animation's most recognizable roles.

The upcoming Family Guy Halloween special, titled Happy Hell-o-ween, features Kieran Culkin as the Devil. The first trailer shows Brian and Stewie heading into Hell after 24 seasons of bad behavior, where they eventually irritate the ruler of the underworld enough to take charge themselves. Hulu confirmed Culkin's casting during the show's San Diego Comic-Con panel in July, and the trailer now gives viewers their first extended look at his performance.

The setup places Brian and Stewie in an unusual position as they attempt to run Hell after their encounter with Culkin's Devil. The preview teases fiery landscapes, classic infernal imagery and the kind of escalating absurdity that has become central to the series. A mariachi band also appears in the trailer, adding another deliberately strange touch to the chaos.

Culkin arrives with a strong comedy pedigree of his own, while his acclaimed role on Succession gives the casting an added layer of recognition. His Devil becomes the latest celebrity guest appearance in a franchise that has regularly used familiar voices to heighten its cutaway humor and pop culture satire.
