Scoop: Paul Bettany Abruptly Drops Out of Showtime's Masters of Sex

Paul Bettany has suddenly lost his appetite for Sex.

The Beautiful Mind thesp has abruptly pulled out of his leading role in Showtime’s buzzy drama pilot Masters of Sex, sources confirm to TVLine.

The project, which would’ve marked Bettany’s first major foray into American television, is based on Masters of Sex: The Life and Times of William Masters and Virginia Johnson, The Couple Who Taught America How to Love, Thomas Maier’s book about the 1960s human sexuality pioneers.

It’s unclear why Bettany backed out. The search is on for a new actor to play William. The role of Virginia also remains uncast.

Reps for Showtime and Sony TV declined to comment.
