Let’s establish that this print is of good quality vision, not bad sound, it’s 1929, the year of the crash, sound is appearing in films, plus it has Louise Brooks, plus it’s precode for a few years so was often risque at that time.

The film launched William Powell but was the time Louise refused to speak … it was badly dubbed later when Louise refused to come back to Paramount to do it. She was not a happy girl. I went to a few bios of her, some more searching … she was abused at nine and was a mess thereafter. Till her death.

Not a great film but that’s hardly the point … this is cinematic history.
