We haven't read the script or anything, but from the name alone, this seems like a pretty good career move for Paul Bettany.
As confirmed by Variety, the British actor has signed on for the Showtime pilot, "Masters of Sex." Bettany will play William H. Masters, a gynecologist who, along with Virginia E. Johnson, formed the Masters & Johnson team that made groundbreaking advances in the study of human sexuality and sexual disorders.
Bettany has largely been a big screen actor through his career, starring in such films as "A Beautiful Mind," "The Da Vinci Code," "Priest" (though he may wish to forget that one) and this fall's "Margin Call," the financial thriller in which he was the standout star amongst a world class cast.
In fact, Bettany joins a long line of big screen actors who have or will be making a substantial foray into television; check out a list of some other big-to-small screen stars in the slideshow below.
