Totally delightful. Hepburn and Grant have great chemistry together, and they scamper through a whip-smart, twisty script. Even better, I was able to fully appreciate all the twists, since this is one of those older movies that hasn't been spoiled unto death by reference in pop culture.
I think Charade is a very overrated movie because there are a lot of loopholes and logical inconsistencies in the scenerio. Also, movie has considerable amount of shooting mistakes. Not best performance of him but Grant's acting is very good in comparison to Hepburn's immature acting. It is not so hard to guess fetishism of Audrey Hepburn as a stilistic icon is the reason of this overrated film.
Pretty good fight scene also. Better hand to hand (or claw) action then most of the James Bond fights. You could tell it was made by a choreographer (in Stanley Donen) and as Jackie Chan says; film fight action is just like dancing.
