I know the answer before I even ask, but why why why is Scarlett Johansson in this? I'm sure that tiny pistol and total lack of superpowers is definitely going to save the world.
Her cocking her pistol is definitely the comedic relief of the trailer. But, in all seriousness, if she's not going to show more cleavage or accidentally get caught coming out of a shower, well then she better have a bigger gun hidden somewhere!
