The Black Scorpion (1957) Goof
Pete Peterson performed the majority of stop-motion animation on The Black Scorpion. Wah Chang created the gruesome slobbering live-action puppet-head thing. I scrolled through the film on my iPad the other day and scrutinized some of the animation. I noticed a film flub. If you look close at approximately 1:15, there is a steam engine passenger train tooling along down the tracks infested with giant scorpions. Someone (Pete Peterson perhaps) has scratched or inked over the label on the side of the coal tender (see yellow arrow, below).
Later, when the scorpion attacks the train we see the origin of the model!
They don’t make ’em like they used to!
