George Clooney has told USA Today‘s Susan Wloszczyna (a.k.a. “Suzie Woz”) that Alfonso Cuaron‘s Gravity “is a very odd film, really. Two people in space. No monsters. It’s more like 2001 than an action film.”

Clooney and costar Sandra Bullock play astronauts working on an orbiting space station. “A satellite blows up and space junk causes damage,” Clooney explains. “We go out in space suits, and she and I are tethered together, floating through space. [So] it’s a two-hander with only two actors in the whole film.” Oh, and “Sandy is the lead.”

Gravity began filming last May in London, and reportedly cost about $80 million — not that much for a sci-fi FX flick. Clooney said that an early cut was recently screened for Warner Bros, executives. The studio will open Gravity on 11.21.12. The Wiki page says it wasn’t shot in 3D but converted to 3D in post-production.

“It is the first time I’ve been in 3-D and, hopefully, the last time,” said Clooney.
