Duplicity is excellent movie from 2009. Duplicity is by far one of the best online movies I've ever watched. Duplicity provides a great pleasure from watching it online. The film is interesting, it does not get boring, it does not get long and although it is not an original production, good acting and skilfully written script make it worth watching. This movie is different, thanks to director. Praise him for it. Feel free to play the movie online or download it to your computer.
