Deep in the Valley (2009) is a sex comedy without sex.  There are topless scenes, but not from any of the major characters in the storyline.  The concept is interesting: two guys are transported to an alternate porn world – something like a porn version of Pleasantville (1998).  The first half of the movie is mildly interesting.  The second half is a letdown, with the characters doing things or going to places with no reason (or I failed to understand it).  Since Pleasantville is an excellent movie, I think the great potential in this concept is wasted.
