Having seen 2001: A Space Odyssey in theaters recently, I was struck at just how intense Dr. Frank Poole’s lost-in-space sequence was — but my main takeaway was how much more excited I now am for Alfonso Cuarón to create a feature-length version of this terrifying moment. Speaking with The Huffington Post, the director opened up on the (few) similarities between his film and Stanley Kubrick‘s masterpiece, saying, “The two things they have in common: The approach is to do something that is realistic. Very realistic. I mean, we thought it should feel as if you’re watching a Discovery Channel documentary on what went wrong. And Kubrick was — even if he was dealing with the future where technology doesn’t exist right now, he was so meticulous about it. But I think that’s where the similarities end because Kubrick’s film is an almost philosophical piece.”

Now, after an initial trailer and the full Comic-Con 2013 panel, Warner Bros. is gearing up promotion on the Sandra Bullock and George Clooney-led 93-minute film ahead of a Venice Film Festival bow next month and they are doing something a bit outside of the box. On the official site for the film, there are three countdown timers for the film, leading up to three separate trailers/clips for the space thriller. Check out all three below, which find Bullock and Clooney running out of options in a terrifying scenario, as well as three new banners.

Synopsis:

Dr. Ryan Stone (Sandra Bullock) is a brilliant medical engineer on her first shuttle mission, with veteran astronaut Matt Kowalsky (George Clooney). But on a seemingly routine spacewalk, disaster strikes. The shuttle is destroyed, leaving Stone and Kowalsky completely alone—tethered to nothing but each other and spiraling out into the blackness. The deafening silence tells them they have lost any link to Earth…and any chance for rescue. As fear turns to panic, every gulp of air eats away at what little oxygen is left. But the only way home may be to go further out into the terrifying expanse of space.

Gravity opens on October 4th.
