The first trailer for Alfonso Cuarón had many on the edge of their seats, now just days after the director and Sandra Bullock stopped by to present new footage from the film at the Gravity panel at the San Diego Comic-Con, Warner Brothers released a brand new trailer, or a clip as some may call it.

The new trailer focuses on two astronauts (played by Bullock and George Clooney) and the disaster that befalls the crew of a space shuttle orbiting over Earth.

Could an astronaut survive in space removed from his spacecraft? One of the few filmmakers capable of bringing this question to life could be Children of Men‘s Alfonso Cuarón.

Director Alfonso Cuarón, producer David Heyman and star Sandra Bullock (in her first Comic-Con appearance) comprised Saturday’s San Diego Comic-Con panel to answer that question.

Cuarón described the story of Gravity as being about two astronauts stranded in space, and that the entire shows the faces of only Bullock an her co-star George Clooney. The director wants the audience to feel as if they’re really floating in space, so he sought to create a truly immersive experience. Before rolling a clip, he noted that in the trailer, the marketing tam used loud explosions, yet there’s no sound in space, so those sounds aren’t included in the actual film.

Day one of San Diego Comic-Con was host to a meeting of three of the best directors working today, as Entertainment Weekly brought fans a discussion of all things movies with their “Visionaries” panel. On hand to discuss their work was Edgar Wright (The World’s End, Scott Pilgrim Vs The World), Alfonso Cuaron (Gravity, Harry Potter and the Prisoner of Azkaban), and Marc Webb (Amazing Spider-Man).

The panel was a chance to hear the directors talk about the process of their current films. Cuaron spoke at length about the issues they had simulating the zero G conditions needed to film Gravity, including creating a special room that was just an empty box that a camera would move around in. He also talked about how Gravity stars George Clooney and Sandra Bullock would try to imitate the director’s Mexican accent (he said though that they sounded more Cuban than Mexican). Cuaron explained how Steven Spielberg’s Duel was a big influence on Gravity.

Webb also spoke of similar issues that went into the filming of the Amazing Spider-Man 2. Webb talked about using Electro as a villain not just because of his powers, but also because it forces Spider-Man to think of creative ways to defeat him. Webb was also excited to show off the visuals of Electro, which is something that drove him to use him as the villain. Webb then spoke to how the documentary Fog of War influenced Amazing Spider-Man 2.

We just saw the first poster for Gravity, the new movie from acclaimed director Alfonso Cuaron, and now comes the first trailer for the movie. It stars George Clooney and Sandra Bullock as an astronaut and medical engineer on a mission is space when things go very, very wrong.

The last time the acclaimed Mexican filmmaker Alfonso Cuaron immersed his storytelling gifts in the genre of science fiction the result was the dystopian masterpiece Children of Men, arguably one of the greatest films made so far this century. Thus when he decides to take a return trip to the realm of the fantastic and impossibly possible it should a cause for celebration.

Warner Brothers has released the first poster for Gravity, Cuaron’s next sci-fi feature, via Twitter, and you can check it out below.
