Lee Marvin's "Slob" character alone makes this worth viewing, although the espionage film is a bit talky and stagy. Still, Marvin is a real hoot, right from the beginning, and provides a few neat surprises near the end. "Slob" is the name of his character, and it fits.
Otherwise, the film is an insult-fest with everyone trading barbs at one another. Some of them are pretty funny. Keenan Wynn as "George," the diner owner, is involved in many of the put-downs but Terry Moore has a lot of good lines, too. They reminded me some good film noir dialog.
Moore plays the blonde bimbo, "Kotty," a self-proclaimed "hash-slinger" who has good looks and figure and isn't as dumb as she sounds. The guys all call her "tomato" during the story, a popular slang term for babes back in the '50s. All the guys in here are hot for Kotty, and you can't blame them.
Several characters in here aren't who they appear to be, beginning with Frank Lovejoy's professor role, so the movie does keep you guessing.
This is an odd film, a B-atmosphere with an "A" cast. It includes some strange scenes such as the goofy weight workout at the diner with Marvin and Cobb, and later a dry-land snorkel-thon between Cobb and Whit Bissell. Speaking of the latter, Bissell is a familiar face. He did a ton of TV shows in the 1950s through the 1970s. I saw him on a number of Lone Rangers episodes but he also had multiple appearances of Wagon Train, Peyton Place, The Virginian, Perry Mason, World Of Disney, The Rifleman and many, many more shows.
This is one of those strange films where overall, it sucks - let's face it, but many individual scenes make you just laugh out loud, meaning it had enough entertainment to have made my (and others here) time watching it worthwhile......barely.
