Watch Duplicity Movie

I was at the bus yesterday and I saw a graffiti on the seat that says watch Duplicity online for free. Then the text had a drawing of a computer monitor. I found it funny but I also got curious what the movie Duplicity is about and why I should watch Duplicity online. I discovered that this movie starts Julia Roberts and Clive Owen in an action, thriller movie. I did not need to know the story anymore, anything with Julia Roberts is a good movie to watch for me. I'm going this weekend with my friend to watch Duplicity in the cinema. See you there.
