Imagine if all of a sudden things in space shifted slightly and we discovered another planet that was just like ours. How would we react? What would we do first? Who would be the first ones to travel there? Would we travel there?
All these questions and then some make up just part of the wickedly imaginative sci-fi romance 'Another Earth,' which is one of several films screening at the 2011 Sundance Film Festival that uses a low budget to blend genres while presenting very relatable relationship stories that are infused with a sci-fi twist. Thankfully, 'Another Earth' is one that pulls this off with great success -- an emotional roller-coaster ride that focuses on identity and questions how much we know about ourselves, as well as how much more we're willing to learn ... or forget.
