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.
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.
This is the first film starring Jean Gabin playing an old timer gangster pulling a heist, his last one, where he has an accomplice helping him getting into a vault from the outside. The other film, made four years later, is called Le Soleil Des Voyous.
