Duplicity opens in UK cinemas on 20th March, but Rotten Tomatoes UK is giving one lucky winner and their guest the chance to see it at its London premiere on 10th March -- along with an exclusive opportunity to meet and greet stars Julia Roberts and Clive Owen!

From writer/director Tony Gilroy, Roberts and Owen star as spies-turned-corporate operatives in the midst of a clandestine love affair. When they find themselves embroiled in a high-stakes espionage game, they discover the toughest part of the job is deciding how much to trust the one you love.

On the evening of the 10th March, the stars will descend on London's Leicester Square for the film's premiere and you could be in with a chance of rubbing shoulders with them if you can answer the following question:

Which film released in 2004 also starred both Clive Owen and Julia Roberts?
