Slow start, but a great movie...
I had a hard time understanding the whole plot of this story. Apparently, Cary Grant's character is mistaken for a spy and kidnapped by James Mason's character and his gang. But this "spy" doesn't even exist, and it's up to Grant to survive and get these guys. He gets chased by a crop duster, gets mistaken for a murderer when the man beside him at the United Nations gets stabbed, and goes across Mt. Rushmore with Eva Marie Saint's character, who plays a spy and his eventual ladylove. This is full of suspense, despite its slow start. All actors play their parts well, and look for the usual Hitchcock cameo somewhere in the movie.

A truly enjoyable masterpiece...
Mistaken by a couple of hired thugs for an international spy and innocent in the murder of a diplomat, Cary Grant (armed only with undeniable charms and seductive shape) flees across the most audacious places of the United States, pursued by appropriately menacing villains (led by suave cold-hearted head James Mason and his henchman young Martin Landau) and shadowed by government agents... Somewhere in between is the sophisticated, glamorous and mysterious femme fatale Eve Kendall (Eva Marie Saint), whose unpredictable devotions tremble between the extremes of good and evil...

Will Grant slip away from his would-be killers? Does he clear his name after falsely being accused?

Directed by a genius behind the camera and a "master of suspense," and featuring intrigue, comedy, romance, and danger--the crime at the U.N., the lethal crop duster attack in the middle of nowhere, Grant's unusually good exhibition at a Chicago auction, the sequence at an automobile plant, and the impressive climactic hunt across the Presidential faces carved into Mount Rushmore--Hitchcock celebrated his golden effort with his fourth and final masterpiece after 1954's Rear Window, 1958's Vertigo, and 1960's Psycho.

The Greatest Hitchcock Movie and the Greatest Cary Grant Movie
Easily the best Hitchcock or Cary Grant movie ever made--filled with suspense and comedy throughout. It works as well today as it did almost 50 years ago and doesn't seem dated. This movie can be watched over and over again with great pleasure. By now you know the classic cropduster scenes and Mt. Rushmore scene, but there are other great parts of the film as well. Other than it maybe being a bit long during the love scenes, this movie is picture perfect.

It's one of my top five movies of all time.

Can't Believe I'm Just Now Viewing This
I've avoided this movie for years. I don't really know why, but what a mistake! The storyline may seem tired by today's standards because we've all seen it before. However, the acting, the lines, and the photography are outstanding... especially the photography!! There were some scenes such as as when Grant and the traveler are waiting on the bus to arrive that are just breathtaking.

Hitchcock and Grant!!
Cary Grant has to be the quintessential Hitchcock male (if Grace Kelly is his blonde)! So suave and charismatic, he is just splendid as the playboy who is mistaken for a government agent. This mistaken identity (a favorite plot point for Hitch) leads Cary Grant on a cross country journey that culminates in one of the most unforgettable cinematic scenes at Mt. Rushmore.

Eva Marie Saint is splendid as the double agent helping and bumbling Grant along the way.

This is a truly great film: filled with comedy and mayhem, as well as murder and political intrigue. Anyone could fall in love with this movie.
