Buzz Aldrin 'impressed' by Gravity

Astronaut praises film's realism.

George Clooney gets it right in Gravity

Buzz Aldrin has become the latest high-profile fan of Alfonso Cuaron's upcoming space-set drama, Gravity.

One of the first astronauts to float in space and the second man to walk on the moon, Aldrin gave The Hollywood Reporter his verdict on the film, saying he was "extravagantly impressed" by the portrayal of the reality of zero gravity.

"Going through the space station was done just the way that I've seen people do it in reality," he said.

"I was happy to see someone moving around the spacecraft the way George Clooney was. It really points out the degree of confusion and bumping into people, and when the tether gets caught, you're going to be pulled - I think the simulation of the dynamics was remarkable."

But Aldrin did point out a few inaccuracies in the film, acknowledging that realism may have been sacrificed for the story.

"The spinning is going to happen - maybe not quite that vigorous," he added. "And we were not as lighthearted as Clooney and Sandra Bullock. We didn't tell too many jokes when people were in some position of jeopardy outside the spacecraft, but I think that's the humanity coming through in the characters."

He went on to point out that the view of Earth from the cosmos isn't quite as crisp and clear as Cuaron has imagined it.

"If you're looking down at Earth, you're looking through an atmosphere that has a bit of haze in many places and not just occasional clouds," he continued. "You might need a pretty good spy telescope to see that well."

Aldrin added that he hoped the film would have a positive influence on advancements in future space exploration.

"We're in a very precarious position of losing all the advancements we've made in space that we did 40 years ago, 50 years ago," he said. "From my perspective, this movie couldn't have come at a better time to really stimulate the public."

Gravity hits cinemas on 10 October, 2013.
