The film, which is currently being called Summer 2006 Project, will also star Tom Wilkinson and an actress who has yet to be named.
The movie follows the story of two brothers with serious financial problems. When a third person enters their life and convinces the two to turn to crime to solve their problems, their lives go from bad to worse, and the two brothers become enemies.
Filming on the project is set to begin in the next few weeks in London. It will be the third movie that Allen, who has always worked in New York, has made in London. The other films made in England by Allen were Match Point and Scoop.
