Trivia: The animators created many small flaws in the film in order to emulate the looks of old comics. This includes color separation and a slight double-image effect in certain scenes to replicate imperfect comic-printing techniques. While the effect was intentional, many film-goers who saw the movie in 2D actually complained about these effects, thinking they were accidentally sold tickets to a 3D movie. (Especially due to the double-image effects).
Trivia: The movie is set in 1987. This is the same year the original "Transformers" cartoon series ended.

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: Although the post script states Dora Block was killed in the raid, she had been taken to hospital a few days earlier and wasn't present. She was murdered by the Ugandan Secret Police in reprisal a few days after the raid.
