Family Guy premieres Halloween special with Kieran Culkin as the Devil

Family Guy will air a Halloween special on Hulu on Oct. 5, and the new trailer reveals that Kieran Culkin is voicing the Devil for the first time. The episode, titled “Family Guy: Happy Hell‑o‑ween,” drops a week before the holiday and promises the show’s trademark mix of satire and slapstick with a supernatural twist.

The series has marked Halloween with original episodes since 2006, turning the holiday into a recurring brand for the long‑running cartoon. This year’s special arrives as Hulu pushes more exclusive content to keep subscribers engaged in a crowded streaming market. The network has been leveraging familiar franchises, and a high‑profile guest star like Culkin helps generate buzz. Culkin, known for his roles in “Igby into the Wild” and “Succession,” adds a fresh voice to the show’s roster of celebrity cameos.

The trailer shows the Devil arriving in Quahog and immediately causing chaos, from turning the Griffin kitchen into a fiery mess to tempting Peter with a “deal you can’t refuse.” Showrunner Alec Bacall and creator Seth MacFarlane have hinted that the episode will parody classic horror tropes while delivering the series’ usual pop‑culture references. Early reactions from fans on social media have been enthusiastic, with many praising the choice of Culkin and the teaser’s dark humor. Hulu’s marketing team expects the special to draw strong viewership, citing past Halloween episodes that have consistently ranked among the platform’s most‑watched releases.

After the Halloween special airs, Hulu will add it to its on‑demand library, allowing fans to rewatch it throughout the season. The move also sets the stage for potential future holiday-themed episodes, a strategy the network has used to extend the life of popular series. For now, viewers can expect a devilish mix of laughs and scares as Family Guy returns to the spooky side of animated comedy.
