Sony Pictures has unveiled the first two trailers for the sci-fi horror thriller Life, just in time for Halloween. Written by Deadpool and Zombieland scribes Rhett Reese and Paul Wernick, the film revolves around the six-member crew of the International Space Station as they come into contact with the very first evidence of biological life on Mars—a small, single-celled organism. As they begin to research the specimen, however, this “life” proves far more dangerous than they could have ever imagined.

The cast of this thing is terrific, with Jake Gyllenhaal leading an ensemble that includes Mission: Impossible – Rogue Nation breakout Rebecca Ferguson, Hiroyuki Sanada, Olga Dihovichnaya, Ariyon Bakare, and Ryan Reynolds. What’s interesting about these trailers—both the domestic and slightly scarier/better international one—is that the film embraces the lack of gravity in space, refusing to create some sort of simulated gravity device that allows the actors to move normally. Much like The Martian and Gravity there’s plenty of weightlessness involved, and I’m curious to see A. Whether it lasts the whole film and B. How they pulled it off.

Story-wise, the film looks pretty promising. Director Daniel Espinosa has been hit-or-miss as a filmmaker—he directed the Reynolds-fronted 2012 thriller Safe House as well as 2015’s star-studded dud Child 44—but with Life, it’s possible he’s embracing the horror genre full-throttle. The involvement of Reese and Wernick is certainly curious, and I’m very interested to see what kind of tone the overall film hits. If this is a straight-up sci-fi horror film in the vein of Event Horizon, all the better.

Check out both trailers below. Life opens in theaters on May 26, 2017.

Here's the official synopsis for Life:

Life tells the story of the six-member crew of the International Space Station that is on the cutting edge of one of the most important discoveries in human history: the first evidence of extraterrestrial life on Mars. As the crew begins to conduct research, their methods end up having unintended consequences and the life form proves more intelligent than anyone ever expected.
