The Last Duel-star Jodie Comer is all set to headline Adam McKay's upcoming limited series, Big Swiss.

Based on Jen Beagin's upcoming book of the same name, Big Swiss follows a woman who after starting a new life anonymously transcribing sex therapy sessions in New York, becomes fixated with one of the patients, leading to an obsessive, explosive relationship between the two.

Comer will play Flavia, a.k.a, the titular Big Swiss in the series. The HBO series is produced by A24 and McKay's Hyperobject Industries.

Comer will also executive produce along with Beagin. Comer is coming off the fourth and final season of Killing Eve. Last year, the actor starred in Free Guy and The Last Duel.
