Alfonso Cuarón has had nothing but bad luck with his developing space film, Gravity. The lead role has bounced from actress to actress, and it’s on the move again. Originally, the part was written with Angelina Jolie in mind but the actress opted not to take it, then Scarlett Johansson and Blake Lively were mentioned as possible replacements, before Natalie Portman agreed to star. Unfortunately, Portman is no longer attached and according to Deadline, Sandra Bullock might take her place.

Sources claim that Portman “mulled” over the role before saying no. She’s also said to have left Pride and Prejudice and Zombies as well, with scheduling conflicts being the main reason. She and Sandra Bullock were the top contenders mentioned for Gravity after Jolie left, and now we’re hearing that the Oscar winner has been offered the part. The question is, will Bullock say yes?

Gravity will be a 3D tale that centers on a woman stranded on a space station after satellite debris slams into it and wipes out the rest of the crew.” Robert Downey Jr. previously signed on to star in a supporting role and now that the studio has given Cuaron the green light to direct the $80 million project.

Out of the batch of actresses mentioned, Bullock sounds like the best choice. She can play a believable mother and it would be interesting to see what magic her and Cuaron can make.

What do you think of Portman leaving? Should Bullock replace her?
