FILM: Julia Roberts = Con Artist?

I think maybe watching George Clooney, Brad Pitt, and Matt Damon have all the fun in the Ocean's trilogy has influenced Julia Roberts's decision to join Billy Bob Thornton, Clive Owen, and Tom Wilkinson (Michael Clayton) in the spy thriller Duplicity. She will play Owen's "longtime lover and rival corporate spy" a la Mr. and Mrs. Smith. The basic plot of the movie is their elaborate plan to pull off a stellar con. Both Wilkinson and Thornton will play CEOs. I've never perceived Roberts as a thieving character, but maybe this is her way of reinventing her career. It's about time she stop being America's Sweetheart--that's Reese Witherspoon's job (even though I'm positive after watching Cruel Intentions that she's got a mean streak).
