If you loved Lâchez les monstres, try Le Cercueil vivant
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 Gordon Hessler, and they both carry the dread mood tag, and they sit in Horror territory. If that's the register that drew you to Lâchez les monstres, the second film will land in a comparable space — through a different lens.

What Le Cercueil vivant is
London, 1865. Heavy rain. A locked trunk. Inside: a disfigured man, hidden from the world by his brother. But secrets claw free. Soon, madness and murder stalk the gentry. A minor-key Vincent Price vehicle with surprising gore.
