The 2020 film Underwater features menacing sea monsters of every caliber, even the remarkable god-monster Cthulhu. A sci-fi horror movie, the film follows a group of researchers on a job site for the drilling company Tian Industries at the very bottom of the Mariana Trench. Everything quickly goes awry as an earthquake hits the underwater facility and the team scrambles to survive. As the haze of the geological phenomenon alleviates, a new terror approaches in the form of unknown creatures lurking in the depths of the trench.

Starring Kristen Stewart as mechanical engineer Norah Price, Underwater creates an air of terror and intrigue to what is lying in the depths of the darkest pits of the ocean and sea. With elements of Lovecraftian horror and Ridley Scott’s 1979 film Alien, Price is the film’s Ellen Ripley, but faces an even more elusive and threatening predator. The creatures at the bottom of the trench are ancient and when Kepler 822 drilled into the earth, they woke up.

In this exclusive clip, director William Eubank and visual effects supervisor Blair Clark go behind the scenes and discuss how the creature was created. While Norah Price may be the film’s protagonist, the underwater antagonists were thoughtfully designed and crafted to make Underwater the horrifying and thrilling film that it is.

Considered a fellow cast member, the sea creature’s movement was integral to the overall production of the film. It had to resemble something that may lurk in the bottom of the Trench but also had to move and interact as though it was from a realm of nightmares. The creature’s environment dictates how it moves, breathes, and reacts to its surroundings in order to make it an entirely cohesive being. With multiple creatures, creating an array of beings can come as a difficult feat but Eubank and Clark exceed expectations.

Eubank and Clark’s attention to detail is impeccable, as this ensures the creature moves as expected and even sounds the way it would if it were dropped on a table. While every film encounters some unexpected changes during post and pre-production, the team for Underwater was well equipped to handle any circumstances.

With a possible sequel in the works, this Lovecraftian creature coming to life in such a detailed and precise fashion is only a portion of what makes Underwater such a great film. On April 14th, the film will release on Digital, DVD, and Blu-ray for audiences to enjoy the spectacular work of Eubank, Clark, and their entire team.
