Charles' house appears to be the last single one left between the new high-rise buildings. His wife was offered 15 Mill. Frs. to tear it down and make room for a new skyscraper. In fact the house is still standing with no more high-rise buildings around but those that are in shown in the film.
The entire heist sequence lasts 26 and half minutes, and has very little dialogue.
Posthumously listed as one of Akira Kurosawa's 100 favorite films.
The film is shot in 1962 and the currency was the new franc at that time. Indeed, two years before, in 1960, France revalued its currency and one hundred francs (old francs) became one new franc.
But people took years to get used to it and orally talked in old francs for years.
In the movie, all amounts are in old francs except for the bills (hotel, massage parlor, bar).
Converted to 2024 values, the amounts are the following: trip to Greece $1500, monthly salary $1300, Charles savings $190,000, house value $290,000, massage parlor $65, amount given to Louis for driving $19,000, daily hotel bill $380, amount of the loot $19 million.
When Charles is spotting his house at the end of the opening credits, he's not really standing in front of it (97 Rue Parmentier) but at the corner of Ave. Auguste Perret/Allée André Ampère.
