Trivia: There's a running gag about Burt wearing a new hat, and how it throws everyone off. And it's true - this is the first film in the series where he isn't seen wearing an Atlanta Hawks hat at some point. (Instead he wears a Chicago Cubs hat). According to the documentary on the Blu-ray of the original Tremors, Burt wore an Atlanta Hawks hat in the first movie because the production had been given a large stock of them, and thus a Hawks hat became a staple of Burt's costume throughout the franchise. Michael Gross himself, however, is from Chicago, and in 2016, between the production of the 5th and 6th movies, the Cubs won the World Series (as mentioned in this film). Thus, Gross, a producer on the films, switched to the hat of his favorite team to honor the championship.

Trivia: Lars requested (demanded) a "Mustang [Boss] 302" from the police to flee the bank robbery. Lars did not specify what year, but 1969-1972 and, possibly, 1973 are relevant to the August 23, 1973 real-life incident. The Mustang 302 was blue and it might seem easy to identify its shade, but that's not the case. Historically, there have been almost 900 colors for the Mustang's paint and there are a variety of blues. "Grabber Blue" was popular when the Mustang 302 emerged, as was "Acapulco Blue."
Trivia: There are several mid credit scenes in the film setting up characters for the follow up film, Rise of the Supermen.

A representative from the Writer's Guild of America even tried to intervene on his behalf, but Disney's rep claimed his script was completely different.
