Trivia: Key Luke actually had to wear old-age makeup to play Mr. Wing despite being about 80 years old at the time, as he looked significantly younger than he actually was. Zach Galligan once asked him how he maintained his looks at his age, and Luke simply replied "No fried food."

Trivia: When Billy is running to work with Barney at the beginning, you can't see it, but Barney actually has a piece of fishing line attached to his collar being held by Billy's actor. The dog kept running away when they'd shoot the scene, so they had to make an "invisible leash" for him. If you look, you can see the dog suddenly speed up a few times... that's because the line started pulling his collar.

Trivia: The dog who plays Barney, whose real name was "Mushroom," reportedly thought that the animatronic Gizmo was a real living animal and would treat it like another dog on-set.
