Jean-Claude Van Damme plays a shady character in the aptly named “Knock Off.”

You have seen “Knock Off” before. And you didn’t like it then, either. Sure, it may have had a different title and maybe a Dolph Lundgren or a Brandon Lee in the starring role instead of Jean-Claude Van Damme. But the premise has always been the same: The charming, vaguely shady hero is caught in a web of deceit where no one is what they claim to be. (In Van Damme’s case, that would be an actor.)
