At the Halloween costume party, Sonia Chapel is wearing the same dress Murdoc (disguised as the French director) gave Penny Parker in Cleo Rocks (1989).
This Halloween themed episode was originally broadcast the night before Halloween.
Included on the Fan Favorites: The Best of MacGyver DVD.
The three helicopters seen outside Jack Dalton's hangar are rather rare Enstrom 28 or 280 "Shark" helicopters which have been commonly used as trainers.
