According to Variety, Marcos Siega has been hired to direct comedy Chaos Theory for Castle Rock Entertainment and Warner Independent Pictures, with Ryan Reynolds set to star.

Inferno Distribution is financing the pic, which producer Frederic Golchan has been trying to bring to the bigscreen for 12 years. The project was originally set up at Warner Bros. Pictures.

The screenplay by Daniel Taplitz is a story within a story about a man who finds out he is sterile and that his daughter was actually fathered by his best friend.

WIP will release the film in North America, while Inferno will handle international rights.

Production is slated to begin in early 2006.
