The new film Gravity spent years in development -- and saw many stars in the lead roles that Sandra Bullock and George Clooney snagged. It’s hard to believe that any one else could play up the same desperation as Sandra Bullock does in the promos that are shown. However, that was nearly almost the case. Natalie Portman was one of the promising names discussed to step into Dr. Ryan Stone’s shoes. Back then Black Swan was all the rage, and it was receiving fantastic reviews for Portman. Of course this role would lead Portman to win her Oscar for Best Lead Actress, but apparently Portman had other plans and declined the role.
... Next up is Angelina Jolie, whose involvement came in 2010 and she was on the top of the director's list for the lead role. In the end the two couldn’t make it work out and Jolie was out of the project.
... Another pick was Blake Lively. Proving to be extremely young, and nowhere near having the acting chops needed to play the role, Lively was approached in 2010 as well.
... George Clooney’s role was once considered by Robert Downey Jr. but passed on the project.
But let's ask someone who knows about the subject: former astronaut Buzz Aldrin. What does he think about the movie?
Buzz Aldrin is a fan: “I was so 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. The spinning is going to happen — maybe not quite that vigorous — but certainly we’ve been fortunate that people haven’t been in those situations yet. I think it reminds us that there really are hazards in the space business, especially in activities outside the spacecraft.” There are just two minor things the film fudged. One, the Earth is not HD-glorious in space. Two, astronauts aren’t that funny. Buzz says: “We were probably 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. This movie gave great clarity to looking down and seeing the features of Earth ... but there weren’t enough clouds, and maybe there was too precise a delineation from space.”
