Okay, so Melville Shavelson was no Sam Fuller or Budd Boetticher or Nicholas Ray. But the sight of a spry and relatively trim James Cagney prancing and tapping around on a big banquet table, and with very few edits to interrupt the action, feels cool right now. (Even with the deeply irritating Pentagon clown Bob Hope huffing and puffing alongside.) Call it a Thursday afternoon mood-pocket thing.
