Jon Petrie, the BBC’s director of comedy, is leaving the broadcaster after about five years to join Hat Trick Productions. Both outlets report that Petrie takes up a Creative Director role at Hat Trick, the independent comedy production company behind shows including “Derry Girls,” “Have I Got News for You,” “Mastermind,” and “Whose Line Is It Anyway?” Deadline also lists several BBC comedy projects credited to Petrie during his tenure, including “Small Prophets,” “Amandaland,” “Dreaming Whilst Black,” and “Such Brave Girls.” The reporting describes the move as a shift from the BBC’s comedy leadership to a senior creative role at Hat Trick. Details beyond the appointment and his previous BBC credits are limited in the provided summaries. No replacement or timeline for the transition is stated in the excerpts, but the announcement frames Petrie’s departure as the end of his five-year stint at the BBC and the start of his work at Hat Trick.
