The 49-year-old actress who stars as engineer Dr. Ryan Stone in the new film was delighted to have been given a part in the thriller where she worked closely with the legendary Mexican director and was
honored that he "trusted" her to take one of only two roles available.
Speaking at the BFI London Film Festival at the Odeon Leicester Square today on Thursday, Sandra exclusively told BANG Showbiz: "Alfonso gave me everything. He gave me the greatest opportunity, the greatest support. He gave me his talent, he trusted me. I can't say enough about that man. He's extraordinary."
The brunette beauty stars alongside George Clooney who was cast as astronaut Matt Kowalski, with whom she embarks on a space mission.
Alfonso was equally satisfied with the small cast, both for their skillful acting ability, as their performance was hugely critical to the success of the film, and their personality.
Speaking from the red carpet Alfonso added: "You're working with only two characters, so all the focus goes there. All the weight of the film falls on their shoulders. They were very precise and detailed in making sure we got the best out of each moment.
"You're working with Sandra Bullock and George Clooney ... You're working with two amazing actors and interesting people. I was in heaven."
The pair were joined on the red carpet by producer David Heyman.
