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. The first Etch-A-Sketch toys were produced on July 12, 1960 and Ohio Art launched the toy in the United States in time for the 1960 holiday season.
Continuity mistake: When Luis is standing in front of the pool table talking to Eddie and his men, there are three pool cues on the table, one on the left and two on the right; when Eddie's men push Luis back on the table, the two on the right turn into one. (Don't get it confused with the one Thay picks up that was the one on the left.)
