Paul Rudd and Zach Galifianakis have joined Paramount's comedy Will, to be directed by Little Miss Sunshine helmers Valerie Faris and Jonathan Dayton.

According to Variety, the story centers on an ordinary guy (Rudd) who lives in a world where people's lives and destinies are being written by scribes in Heaven. The man wakes up one day to find that his heavenly writer has decided to no longer draft his life, and he must go about his day unscripted.

The project is based on a Demetri Martin pitch, which DreamWorks bought pre-emptively in 2006. Paramount took control of the project after the companies split in 2008.

Will is scheduled to begin production in the spring.
