Rule No. 1 when making an espionage film; be it Corporate, Industrial, Political or any kind of espionage don't be BORING. Be interesting! That's gotta be the first rule. By breaking rule number 1 Duplicity fails to be a good movie. Sure its got witty dialog and good anamorphic photography, but as good as Robert Elswitt, ASC, is he's only as good as the movie. Its rubbish that drags on for 2 hours and nearly six minutes. Sure, there's a surprise ending fitting the genre, but its not worth putting yourself through the pains of 2 hours and 6 minutes of this movie. I'll give it the big Corporate espionage sequence, where they're stealing the formula, its pretty tense, but my god, it too isn't worth the time. I actiually thought about doing my quarterlies while I was watching this.
