We've been waiting to see Scarlett Johansson gain superpowers and go on an ass-kicking spree in Luc Besson's Lucy. Now the first trailer is here and it looks like the visual spectacle we've been hoping for.

It seems the movie does rely on the pseudoscientific claim that human beings only use ten percent of their brains. Otherwise, though, Lucy looks wonderfully insane as Johansson goes from a drug mule at the mercy of her captors to a superhuman with remarkable control over her body and a diminishing capacity for mercy. Plus, we get Morgan Freeman as the neuroscientist who attempts to understand what is going on with Lucy's brain.
