If you loved Le Monstre des abîmes, try Les Survivants De l'Infini
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.
Ce qu'ils partagent
Both films are directed by Jack Arnold, and they both carry the 3am cult mood tag, and they sit in Horror / Science Fiction territory. If that's the register that drew you to Le Monstre des abîmes, the second film will land in a comparable space — through a different lens.
3am cult
What Les Survivants De l'Infini is
High desert, late night. A humming capacitor. Two scientists whisked across space to aid aliens in a brutal war. Their benefactors offer advanced technology, but hide a grim secret. A sterling example of widescreen 1950s science fiction.
