Watched May, 2025.
This is a great 1950s (French) heist flick, with fantastic details on how the safe is cracked and the heist is accomplished, and then the aftermath when the thieves fence the jewels and attempt to hang on to the cash. The thieves had to circumvent the security and police tech, which were primitive (but not negligible) in 1955, but when you throw in a couple molls everything becomes beaucoup complicated.
It bugs me when a new movie is made in the 21st century but takes place in the past before modern tech. Cell phones kill every plot of the 20th century; an encrypted email cannot be hacked (no matter what you see on NCIS) and all catastrophes are solved by an easy phone call. Stick with Rififi: the characters are inherently just tough guys with no tech knowledge and it all just makes sense.
