This is the first time Burt Gummer isn't seen wearing his trademark Atlanta Hawks hat. This time he sports a Chicago Cubs hat.
Michael Gross said that he suggested Burt's hat be changed to a Chicago Cubs one out of allegiance to his own home town's team, and also because there was no real reason that Burt wore an Atlanta Hawks hat, other than his own suggestion as well for the original movie.
Burt's shouting "Looks like you broke into the wrong god damn hangar didn't ya you bastard" is a throwback to his "Looks like you broke into the wrong god damn rec room didn't ya you bastard" comment from the first Tremors movie.
Michael Gross was the only person to appear in all six "Tremors" movies. In O Ataque dos Vermes Malditos (1990), O Ataque dos Vermes Malditos 2: Os Vermes Estão de Volta (1996), O Ataque dos Vermes Malditos 3: De Volta à Perfeição (2001),O Ataque dos Vermes Malditos 6: Um Dia Frio no Inferno (2018) and O Ataque dos Vermes Malditos 5: Linhas de Sangue (2015), he played Burt Gummer. In O Ataque dos Vermes Malditos 4: O Começo da Lenda (2004), he played Hiram Gummer, an ancestor of Burt Gummer. He also played Burt Gummer in the TV show Tremors - O Ataque dos Vermes Malditos (2003).
Travis tells Rita to take off her pants. This is a reference to Tremors when Val took off Rhonda's pants to untangle her.
