Visible crew/equipment: The film crew is reflected in the chrome of the right side mirror of Beverly and Murray's car.
Factual error: As Murray and Adam first walk into the VHS rental, a pan shot displays a cardboard cutout of C-3PO and R2-D2. The cutout features artwork from the TV series "Star Wars: The Clone Wars" which first aired in 2008, where as "The Goldbergs" take place in the 1980's. (00:04:30)

Other mistake: In this episode, Adam watches Die Hard for the first time. Earlier in season 2-1, he is shown wanting to watch Die Hard. Die Hard wasn't released until 1988 and the Goldbergs would have at least had 3 Hanukkahs before this episode. This is impossible considering the time frame at to be watching it at both times.
