Daryl Hannah, Tom Sizemore, and Thora Birch have all joined the cast of Snuff, an adaptation of Chuck Palahniuk's novel of the same name.

The story centers on an aging porn star, Cassie Wright (Daryl Hannah), who tries to set the record for the biggest gang-bang in history by having sex with 600 men in one day. Tom Sizemore will play Mr. 600 and Thora Birch will play Sheila, Cassie's personal assistant. Here's the description of Chuck Palahniuk's novel below.

"From the vantage point of three men waiting in line to be three of the 600 men Cassie Wright plans on having sex with on camera to break a world record, Snuff is not for the shy and reserved.

Number 600 is the man who introduced Cassie to the industry and the man who introduces us to the rest of the men waiting in line. Number 72 is not only one of the youngest ones there--20 something years old--but he is one of the too many men claiming to be Cassie's son. The last man, number 137, has been in the television biz and is looking to get his career back on track by screwing an on-the-verge-of-being-dried-up porn queen.

This is not a sex novel--sorry, gentlemen. It is a story of men bonding over a similar interest, getting to know one another through their future sexual conquest, and, for a few, trying to find--and twistedly bang--their misplaced mother. There is a surprising lack of sex for a novel about a porn star and her 600 exploits. But don't be turned off by this. There's still some sex, plenty of laughs, and some telling moments as each of the three main narrators finds something buried deep within himself."

Fabien Martorell will direct this adaptation, from a script he is co-writing with Karina Wilson. No production schedule was revealed.
