Asphalt Jungle Meets Written In The Wind
This movie is a blend of heist movies like "Asphalt Jungle" or "The Killing" with sexy soapers like "Written In The Wind" or "Peyton Place".
You've got 3 bad guys (McNally, Marvin & Naish) planning a bank heist. You also have a handsome, rich alcoholic (Egan) who can't live up to his father's standards and who's wife (Hayes) has "two or three hobbies a year", while his hard working subordinate (Mature) is asked to keep an eye on him.
There are also enough subplots to make several other movies. The librarian who steals, the voyeuristic bank manager who likes to watch. The father who didn't fight in WWII to his son's shame. The pacifist Amish family.
You could have made an entire TV series out of this.
It's filmed in intense technicolor cinemascope on location, so it doesn't qualify as a noir.
The cast does fairly well, especially Lee Marvin and a surprisingly good Victor Mature. I think it would have been even better if Robert Stack had played the alcoholic rich guy and Dorothy Malone his oversexed, trampy wife. Stephen McNally is OK as the leader of the bank robbers, but Sterling Hayden or Robert Ryan would have been even better.
