Allen keeps film details from actors

Coleraine-born James Nesbitt is about to start making Woody Allen's first British film, but don't ask him what it's about.

Nesbitt, whose career will really take off with this project, joins Scarlett Johansson, Jonathan Rhys-Meyers, Brian Cox and Emily Mortimer in "a high-society romantic comedy".

But Allen is keeping the exact details of the plot so secret that he has even refused to let his cast know what it's all about.
