UPDATE: Warner Bros has confirmed that George Clooney is set.
UPDATE: Insiders say that Warner Bros is making a full court press for Sandra Bullock to play the role of a space station team member who tries to find her way back to earth and her daughter after the space station she is working on is destroyed by a debris field from an exploded asteroid. Bullock, coming off the Oscar win for The Blind Side, certainly has the drawing power and the chops to hold the screen. Numerous actresses have wanted to make the film because it is ambitious and original, and also because for the opportunity to work with director Alfonso Cuaron, which is a major reason Robert Downey Jr. agreed to co-star. Portman’s reps confirmed that she won’t star in Gravity, citing scheduling conflicts.
