Duplicity (2009) stars
Julia Roberts and
Clive Owen as CIA spooks Claire Stenwick and Ray Kova, who hire themselves out to two companies each out to steal a valuable trade secret. As they each conspire to get to the prize first, Stenwick and Cova discover a mutual attraction that threatens to get in the way of the job. Amidst all this espionage, the real mystery is whether the ever-so-brief side boob we see when Julia gets out of bed is hers or a body double’s. If it's the latter, that would be duplicitous.
