Director William Castle, upon seeing the end results of this movie of his, seemed to have realized that this movie wasn't up to his previous movies. For one thing, the gimmick that he came up for this movie was to give patrons a copy of the coin seen in the movie. (Whoopie!) *I* certainly thought that this was one of his weakest efforts.
The premise of the movie, while not really original (even when the movie was made), still did have some promise. But there are two main problems that shoot down the movie. The first is that the characters act pretty stupid for most of the movie. Our hero is a college professor, yet the coin-related actions he does suggest he has put little thought into what he has discovered and what he should do with it.
The second problem is related to that first problem, in that most of the movie is devoted to him *not* using the coin to his advantage (which is what most people would do), or being responsible with the coin. You will keep wondering just when some conflict will come into the movie, and he will be forced to struggle, to bring some ACTION into the movie. Eventually (after more than an hour of the running time has passed), our hero is challenged, but he acts (again) so stupidly when someone with even average intelligence would figure out how to use the coin to end the conflict in just a few minutes.
Not even worth two cents.
