I Love You, Man is the first laugh out loud movie I have seen this year. Often hysterical and always enjoyable, it's a very entertaining comedy.
Duplicity is a movie for people who like to engage their brain while sitting in a movie theater. The script is pretty ingenious and the dialogue is really strong. Clive Owen is the coolest of cats and Julia Roberts was extremely sexy.
Full reviews to come for both, but in short, I really liked both of these flicks.
