If you read up on your Tango & Cash trivia, you may discover that Kurt Russell landed the celebrated role of "Cash" after Patrick Swayze dropped out.
Which makes one wonder: Would it have made much of a difference had Swayze played Cash? My guess? "No." The two actors are basically interchangable - particularly in the early 90s, when casting calls for mulleted everymen always caused both Swayze and Russell to surface to the top.
So here's a chance to test your knowledge of Swayzo-Russellean film. You could check the source code or just go to IMDB, but since there's no final tally, it's rather fruitless. Besides, I'm convinced that the two really are the same actor: note that you never see them both onscreen.
