A scientist builds a cloning machine to try and get back his murdered twin brother.
After Earth looks kind of cool, but it's directed by M. Knight Shyamalan, so it will likely be massively disappointing. On the plus side, a new Shyamalan movie means it's time to play "Guess the Twist!" What do you think it will be?
My guess is Shyamalan will "borrow" from older, better sci-fi and this will actually be the story of how humans colonized pre-historic Earth, making the title of the movie almost completely meaningless. What a twist!
