Lots of circuitous fun in Sidney Lumet's adaptation of the Broadway play, in which Michael Caine and Christopher Reeve are unforgettable in a story that involves a highly wanted draft of a play, a house full of weapons, and enough doublecrossing to make anyone dizzy. That house ends up as the real star of the show, a mysterious old mill (complete with windmill) that is home to the film's most unique surprises. And though it's a bit meandering toward the middle, Caine turns in one of a surprisingly great performance.
