"You can't even be honest about being dishonest!"
Charade is a very funny spy/mystery about a dead man, a very large amount of missing money, a threatened widow who is clearly in over her head (Audrey Hepburn), a mysterious man with many names (Cary Grant), and three sinister, shadowy men. This movie has more twists and turns than it should even be possible to fit into 113 minutes, and every time you think you have it figured out, it smacks you in the nose with another curve-ball.
The plot is a successful marriage of humor, murder, and danger. People die at every turn, yet there's a small or big laugh around every corner. Hepburn and Grant really get to flex their comedic muscles, thanks to a script that provides excellent banter for the two leads. Hepburn is her typical beautiful, charming, girlish, impossibly adorable self. No surprises there. And Grant handles both the funny and dangerous aspects of his character quite well, to the extent that you never quite know whether to trust him or not. There's great chemistry between the pair, almost to the level between Grant and Grace Kelly in To Catch a Thief. That's a huge compliment, as I absolutely love that movie.
Charade does a lot of things very well. And while it stays safely on the side of light entertainment, and doesn't quite have the magic of some of my favorite classic movies, it's a fun movie to watch. Do yourself a favor and see this film; there is very little chance that it could possibly disappoint you.
