The opposite poles of Alfred Hitchcock  movies are for me defined by  Vertigo and To Catch a Thief.  Vertigo is relentlessly frightening and you are tense watching it.  To Catch a Thief has strong elements of humor, beautiful scenery and Cary Grant and Grace Kelly flirting a lot.  David Mamet is now the main producer of the first style.  And now Tony Gilroy is a candidate for a producer of something like the second style, with his new movie Duplicity.  A.O. Scott gives it a glowing review.   There is not even a trace of violence in it so it’s even lighter that To Catch a Thief.  I had a lot of fun but I don’t want to oversell it.  Look at the reader comments to Scott”s review!    If you set expectations wrongly, people are disappointed.  But one of the comments has it spot on:  The outside option to seeing Duplicity is I Love You, Man.  Unless, you want to do Dinner and No Movie, Duplicity is your best option.
