Anachronisms are everywhere!

One expects some artistic license to be taken in a movie derived from a graphic novel. But there is a limit. When the news film of the "meteor" destruction in 1920 showed a wrecked mid-fifties car I sort of knew we were in trouble. Important plot points involve a battery-powered tape recorder and a 16mm movie camera and projector. The tape recorder is obviously a 60's or later model and uses plastic reels and tape at a time when no battery models had yet been manufactured and tape was paper based and reels were metal. The movie camera is a Bell & Howell Filmo 70 but a model made much later than 1946. A spring wound camera, it held 2 1/2 minutes of film and could film for about 50 seconds before it had to be wound again. To make his snuff movies our villain would have been doing a lot of reloading and winding. Most importantly, it was NOT able to record sound! Nor could the silent B&H projectors shown play back sound. And that's important because the dialog played back figures in the plot. Additionally, the reels on the projector change in design from shot to shot as does the amount of film on the reels. In one scene the projector is running backward! Yes, the film is being wound to the top reel, not the bottom. The car that the juvenile Sparks parents are killed by is a 46-48 Plymouth. 20 years later when Sparks is an adult he seems to be driving the same car! And that would put the final portion of his story in the mid-sixties! Does he drive an antique car or did the producers have only one classic car at their disposal and so used it whenever an "old" car was needed. More sloppy work; watch as the red Plymouth approaches the Sparks family at the railroad crossing. Its license plates change color several times. This indifference to continuity reduced my enjoyment of the movie and I assume the constant reappearance of the car over the decades confused a few other viewers.
