The Simpsons Treehouse of Horror Fun-Filled Frightfest

HarperCollins’ The Simpsons Treehouse of Horror Fun-Filled Frightfest (2003) is a single-issue comic that brings the show’s beloved Halloween anthology tradition to the page, with Garth Ennis and John McCrea—the team behind The Boys and Hitman—lending their darkly comedic talents to a Springfield-set horror spoof. A unique crossover of Simpsons satire and Ennis’s signature irreverence, it stands as a one-off oddity in the franchise’s expanded universe.
