'Masters Of Sex' Premiere: Showtime Releases Episode Online Two Weeks Early (VIDEO)

"Masters of Sex," one of this fall's most hotly-anticipated new series, is headed to Showtime on September 29, but -- surprise! -- the premiere hit the Internet two weeks early.

Starring Lizzy Caplan and Michael Sheen "Masters of Sex" is based on the groundbreaking 1950s sex studies conducted by Virginia Johnson (Caplan) and William Masters (Sheen). And from what we've seen of it, it looks like Johnson and Masters won't be spending all their time researching.

Watch the "Masters Of Sex" premiere above and, in case you missed it, check out the trailer below.

"Masters of Sex" premieres on Sun., Sept. 29 at 10 p.m. ET on Showtime.
