Natalie Portman was supposed to star in Alfonso Cuarón's Gravity before she dropped out and was replaced by Sandra Bullock. But now that Portman is coming back from her maternity break, she's reportedly considering starring in another spacey movie — the Wachowskis' Jupiter Ascending. Or at least, the Wachowskis are actively courting her. What is Jupiter Ascending about? Nobody really knows — although rumors were circulating a few months ago that it's about Earth colonies at war. Let's hope this really does have some huge space action scenes, and Portman's post-Black Swan clout actually gets it made. Oh, and let's hope there are no long scenes of Colonel Sanders explaining Philosophy 101, too. [L.A. Times]
