Visible crew/equipment: Look over Val's right shoulder as Rhonda is supposedly driving upside down with her legs sticking out the back window of the truck cab and you can see a man driving for her. (00:42:40)
Visible crew/equipment: Towards the end, just after Kevin Bacon says "this one's not falling for it," watch for a boom mike right at the top of the screen.
Visible crew/equipment: As the camera pans up to the roof of Bert's house, a film crew member is reflected in the window.
Revealing mistake: When the lawn mower the heroes send off as a diversion crashes you can see a wire pulling it. (01:01:30)
Trivia: Reportedly, star Kevin Bacon was at a rough patch in his life during production and didn't understand the appeal of the film or the light-hearted comedic elements. (Even once breaking down in public and exclaiming in frustration "I'm in a movie about giant underground worms!") And thus, he chose to have no involvement in the sequels. It wasn't until some years later that he decided to re-visit the film and give it another chance after it became a massive cult-hit, and discovered that he actually really loved it. Bacon has since gone on record saying one of his dream projects would be to reprise his role of Val McKee in a future film.
Chosen answer: The machine is a vibrating case cleaner, which is used to polish the brass casings of pistol and rifle ammo. The "dirt" is actually an abrasive polishing compound.
