Behind the scenes

 * Daphne hums the tune to The New Scooby-Doo Movies theme song while she sews Fred's new ascot.
 * How many times does Velma say "Jinkies"? Once.
 * How many times does Shaggy say "Zoinks"? Once.
 * Danger-prone Daphne moments: She finds a narrow gap in outside the Rung's secret cave, which lets loose a horde of bats.
 * Scooby has every single pizza joint in town tattooed to his tongue. Isn't that a violation of animal rights?
 * Shaggy refers back to the last time they heard Mr. E warn them in "Beware the Beast from Below".
 * The jump the Mystery Machine did while being chased in town by the Ghost Rig is an homage to the Mach 5 in the anime Speed Racer.

Errors

 * Why does Mayor Jones out of the blue make Scooby Chief Officer of Honorary Office of Pizza Affairs? By the way, it's never brought up again after this episode.

Everlasting influence
"Theater of Doom" acts as a sequel of sorts.

Marketing and promotion
