Another Earth is a 2011 film co-written and directed by Mike Cahill, written by and starring Brit Marling.

The story is about a young woman named Rhoda who, upon getting released from a stay in jail, hears reports that NASA has sighted an Earth 2, completely identical to Earth 1. She enters a contest being held which would allow her to fly to Earth 2 and start her life over.

This is a very good little film. It begs the question, if each Earth is identical, how do you know which one came first? Is it not a little presumptuous to assume that your planet is the first, or "real" one? Maybe there is another planet similar in every way to ours. Maybe ours is the copy. Maybe on that other planet, there's another version of you who is living a completely different life. These are all things considered in this film, and it really makes you think.

This is the first film I had seen of Brit Marling's. She has a very organic screen presence, not at all forced or unnatural. She's lovely to watch, and she certainly has a knack for writing unique and thought-provoking films. She asks the audience to engage and to think, rather than to just shut their minds off and let the film do the work for them.

The film is rated PG-13 and has a running time of 92 minutes. If you like smart sci-fi dramas, this should be right up your alley.
