Very happy to hear that Leonardo DiCaprio and Marion Cotillard are currently filming a movie by Christopher Nolan called INCEPTION scheduled for release July 2010. The movie is about a CEO who becomes involved in a blackmail scandal.
There is not that much information about the movie yet, but a month ago they were filming in London and now have moved to Paris. I am sure as the filming progresses so will the information about the film. Stay tuned.
