Olivia Colman is playing a femme fatale who falls for Homer Simpson in the new season of The Simpsons.

The show’s executive producer James L Brooks revealed the casting on Twitter, where he described Colman as “one of the best guest appearances in Simpson’s history. No kidding, I am flying.”

Brooks described Colman’s character as “the most down home femme fatal ever who attracts every man she’s ever met but falls hard, harder than she ever imagined, for Homer Simpson.”

Colman will appear in season 31 of The Simpsons, a date for her episode has not been announced.
