Factual error: Louis Simo gives his son an Etch-A-Sketch while taking him to school, and later when Louis stops by to see his son at his ex-wife's house, his son is playing with the Etch-A-Sketch in his bedroom. Both incidents take place in the summer of 1959. George Reeves died June 16, 1959, hence the investigation.

Factual error: During the big sacrifice scene an eclipse happens. An eclipse occurs when the moon passes between the earth and the sun.

Factual error: One of the subplots involves a young boy ("Tommy") who is bitten by a cobra and the attempts to save his life. When they are working on his arm, it is horribly swollen & filled with fluid which they drain by cutting open his arm. Cobras secrete a neurotoxic venom which attacks the nervous system. It would not cause noticeable swelling at the bite site. The symptoms Tommy has would indicate a bite from a snake which secretes a hemotoxic venom (such as a rattlesnake), which attacks the blood stream & tissues, causing swelling.
