About

Productions Les Montagnes Hallucinées (PLMH), also known as Mountains of Madness Productions, is an independent Canadian production company founded by Vanessa-Tatjana Beerli, screenwriter, director, and programmer, and Pierre LeBlanc, expert in cultural and strategic business management.

Based in Quebec and resolutely oriented toward international markets, PLMH is dedicated to the co-production of genre films, at the crossroads of fantasy, science fiction, thriller, and horror. Each project blends artistic ambition, production rigor, and strong thematic depth.

Our stories are rooted in the major issues of our time: ecological crisis, species survival, social transformations, and the complex relationship between humanity and the unseen. Whether exploring shadowy zones related to consciousness, the environment, or the paranormal, PLMH embraces a visceral, political, and sensory cinema, where imagination serves as a lens to reveal reality.

A specialist in practical effects, PLMH designs physical, mechanical, or hybrid setups integrated into real sets, in order to maintain an organic and immersive aesthetic. This handcrafted approach, developed in-house or in collaboration with specialized creators, enhances the emotional and visual impact of scenes while offering a powerful alternative to fully digital effects.

PLMH has established itself as a key player in auteur-driven genre cinema, capable of bringing to life bold, unsettling, and universal stories.
