"Collateral"
A cab driver finds himself the hostage of an engaging contract killer as he makes his rounds from hit to hit during one night in Los Angeles.
Ruffalo plays det. Ray Fanning who tries to make sense of the rising number of bodies.
I like what he did here. I don't think I know any other Mark Ruffalo character who is as cool as Fanning.
