When Adam is hit by the police wagon on the cross street, a white car in the background moves backwards, indicating that the scene was shot with Adam standing up in front of the car so that it looks like he is falling when played backwards.
When Adam lifts the generator one-handed from Dr. Link, it bumps the back wall, revealing it as a flimsy stage wall. Then Adam shifts his one supporting hand to the edge of the shelf that holds up the generator. The generator swings from invisible wires holding it up.
The issue of Adam being a sentient being or a piece of property never comes up. Since one can't apply the term "murder" to a bit of machinery, it would presume that Adam is a being.
Accounts of the past given in court by Fred and Adam don't match up, creating a Roshomon situation of seeing through people's individual perspectives. Evie Cooper's is clearly inaccurate, as her testimony covers and conflicts with the opening scene of the episode. Mrs. McCrae's testimony, however, is an unknown. It appears accurate, but since Mrs. McCrae is a reactionary character, her testimony shouldn't necessarily be believed (and could have been exaggerated - yet doesn't seem to be).
In lifting Evie out of the pond, Adam breaks her arm, yet she does not scream and shortly thereafter says "The tin man hurt me." For such a minimal, controlled reaction, she must have an unusually high tolerance to pain. It makes her courtroom reappearance in a cast seem contrived.
In the opening scene when the sheriff and his deputies corner Adam Link in a hut, it sounds like one of the men says, "Ugly brute ain't it? Thing weighs more than three hunnert pounds." Then the Sheriff says that it would be too heavy to carry, which obviously would not be true for the half dozen men present. Presumably the figure should have been 3,000 pounds, but the line may have been read wrongly by the actor.
