Fall movie-goers are used to Halloween horror flicks, including torture porn and zombies. This fall, however, the scariest flick may not have a monster of any sort.

Gravity is set to release the first weekend in October, and promises to play on the existential human fears of isolation, hopelessness, and looming death. The movie stars Oscar-winners George Clooney and Sandra Bullock as Astronauts stranded in space suits after debris destroys much of their space shuttle. Bullock is the rookie and Clooney is the veteran who is on his last mission to space. Cut off from Earth and with oxygen reserves running out, the astronauts will have to figure out a way to stay together and survive. The movie was written and directed by Alfonso Cuarón, the director of Y Tu Mamá También and Children of Men.

Warner Bros. this week released a new trailer for Gravity. It shows off some impressive special effects in an early sequence where a disaster sets the movie’s events in motion.
