The Hollywood stars play a pair of astronauts in the space drama and Clooney has now revealed they are heading up a very small cast of two.
He tells USA Today, ""A satellite blows up and space junk causes damage. We go out in space suits, and she and I are tethered together, floating through space. It's a two-hander with only two actors in the whole film. It is a very odd film, really. Two people in space. No monsters. It's more like 2001 (2001: A Space Odyssey) than an action film... Sandy is the lead. And she is beautiful in it. We have known each for way over 20 years. It's fun to work with her.""
Clooney also reveals he is wary of appearing in a 3D film for the first time, adding, ""It is the first time I've been in 3D and, hopefully, the last time. It's (the film is) not near ready yet. They just showed the first cut to the studio.""
