Actress Sandra Bullock has joked how her upcoming thriller film Gravity has a lot of "space sex", which is slower than real life. "Oh my gosh, there’s so much space sex in this film,” accesshollywood.com quoted her as saying. “It’s a lot slower than in real life because of the whole zero gravity thing. But it takes us a good 45 minutes to actually get from beginning to end, so (the audience) might nod out a little bit, but the end, the climax is amazing,” Bullock joked. The actress features alongside George Clooney in the movie.
