Mistranslated title becomes an urban legend
It is in most reference books and, inevitably, in the IMDb. But this movie was NEVER called "The People of Abrimes". This "title" is just a mistranslation, following a typo, of the French release title of the film, LE PEUPLE DES ABÎMES (literally, "The People from the Deep". Someone made this goof way back in the '60s, and English-language publications have repeatedly mentioned it as an alternate title, perpetuating the error.
It's about time IMDb rectified this.
