Tony Scott's hugely entertaining Unstoppable is a tried-and-true Hollywood action flick in which hardworking blue-collar stiffs -- in this case Pennsylvania railroad workers in pursuit of a runaway train -- outsmart and outmaneuver (literally in both cases) the suits in headquarters, whose only interest is minimizing t...he damage to the company's stocks. Denzel Washington, who plays a veteran railman, is a consummate performer who is uncommonly good at playing opposite younger actors, here Chris Pine as the hotheaded and insecure newbie conductor Will. Pine is equally as adept at playing callow youthful studs, who take their lumps but eventually end up saving the day despite their faults. Rosario Dawson as a railyard supervisor, Kevin Dunn as a callous corporate v.p., and Kevin Corrigan as a federal railway inspector each make strong contributions in this story that was leanly crafted by Mark Bomback. Good times.
