Reports confirm that Kieran Culkin will guest star as the Devil in a new 'Family Guy' Halloween special airing exclusively on Hulu. The casting was announced Saturday at San Diego Comic-Con. Both Deadline and Variety agree on the role and platform. However, the reports differ in their framing. Deadline emphasizes that this marks the third straight year the Halloween and holiday specials return to Hulu, and quotes showrunner Rich Appel. Variety focuses on Culkin's casting, noting his 'Succession' character's devilish traits as a fitting background. A factual discrepancy exists: Deadline states the specials return in 2026, while Variety says 'later this year' without specifying a year. Only Deadline mentions a separate holiday special and the showrunner's name. The special will air exclusively on Hulu.
