Points to Mike Cahill for offering an original and thoughtful original film. It was kind of jarring, considering that it seems like a movie needs to be based on SOMETHING (Book, another movie, old TV show, video game...board game, nostalgic childhood candy, etc) and Another Earth reminded me of how much life a film can have when its untethered from the world we know. Cahill does a fine job subverting the film's high concept and focusing on a tragic human drama between two broken people, and uses the sci fi premise to prod at deep philosophical and emotional truths. It's not entirely successful, as the film feels a little bit too melodramatic and loses momentum by the time the third act hits (though the conclusion was satisfying), but it was so nice to see such earnest filmmaking with such naked emotion. Brit Marling is excellent, and props to Cahill for helping William Mapother escape from the shadow of "Creepy Ethan" from Season 2 of "Lost." Even though I wasn't 100% on board with this one, it did make me excited to see Mike Cahill's follow-up--"I Origins"--and everything else he does in the future.
