This fair comedy is mostly notable for its use of the through-the-keyhole camera views that form much of the film. They were not new even in 1903, but this movie does get some credit for using them effectively. The story, though, is just a little too plain to make the movie much more than average for its era.
The story starts with a woman peeking through keyholes in a hotel, expecting to catch her husband in a compromising position. One difference between "A Search For the Evidence" and other films with the same technique is that here the woman has a specific reason for her otherwise voyeuristic behavior.
Most of what follows, though, is only mildly creative. From a technical viewpoint, it works pretty well, with some simple but smooth dissolves as well as the point of view shots. With somewhat more imaginative story material, it could have been pretty good.
