Another Earth presents an interesting experiment; a second Earth suddenly appears in the sky. The mysterious planet is actually another copy of Earth, perhaps one in another universe. Why it suddenly became visible is left unexplained. However for a movie called Another Earth this film has very little to do with this said other Earth and more to do with what this second Earth means to a few individuals in our Earth. No surprise that a second Earth means a second chance to the protagonist Rhoda Williams (Brit Marling).
