Phoenix Pictures is adapting the Robert Heinlein novela, The Unpleasant Profession of Jonathan Hoag, and has attached Alex Proyas to write and direct.

According to The Hollywood Reporter, the film is a complex psychological thriller with plenty of action as well as some love interest. A title change is likely.

Originally published in 1942, the offbeat tale centers on a man who becomes increasingly disturbed when he realizes he cannot account for his activities during the day, or even what he does for a living. He divulges his problem to the husband-and-wife partners of a private detective agency, and their investigation leads to a series of revelations they could never have fathomed.

The project is said to start filming in 2010.
