I must confess to a degree of disappointment after having watched "The Devil Commands" the other night, after several years of waiting to do so. The memory of its excellent source novel, William Sloane's "The Edge of Running Water" (1937), is still very much with me from several years ago, you see, and I'm afraid that the film does suffer in comparison. The book has sharply drawn characters, a well-detailed plot (a scientist attempting to communicate with his dead wife), great suspense and a very satisfying windup. The film, unfortunately, has none of these things in much abundance. Still, there ARE some good things to be said for it. Boris Karloff, as usual, is wonderful, as is Anne Revere in her role as his assistant. The effects are more than passable, and, at a mere 65 minutes, there is no unnecessary padding. Indeed, the film can be accused of being not fleshed out enough! Several things aren't explained; even Boris' fate is never clearly shown, unlike his character's amazing finish in the book. This is a story that is truly ripe for a remake, if done faithfully and by a team that respects the source material. Still, I can think of many more fruitless ways to spend an hour than by curling up with "The Devil Commands."
