- In The Twilight Zone, the radio's sound clips that play during "Fast Lock" are taken from earlier Pat Lawlor pinball machines. In fact, starting the mode when one of the clips is playing cues the multiball theme from the respective machine to play.
- Similarly, hitting the clock enough times during "Clock Chaos" will play a clip of Rudy (from Funhouse) yelling, "Stop playing with the clock!"
- The Wizard Mode in Steve Ritchie's Terminator 3: Rise of the Machines is "Final Battle", which pits the player against the T-X Terminator. At the climax of the fight, Ritchie reprises his role as the voice of Shao Khan to deliver the final instruction:

- After missing the jackpot in the multiball restart, Red says "You missed everything!"
- The Invaders from The Twilight Zone appear during several modes, most notably during the Seattle mode.

- Junk Yard has a lot of them. Examples include:
- One sound effect is taken from Earthshaker!.
- During Crane Hurry-up, the voice saying "Come on, hurry, hurry, hurry!" sounds like one of the voices in Dr. Dude (used for the Gift of Gab, among other things).
- The Angel's voice is the same as the Candy 5000's from Safecracker, and both the Angel's portrait and the Devil's voice are in WHO dunnit
- The backglass indicates that the junkyard itself is located behind Tony's Palace.
- The Super Jackpot animation comes from The Getaway: High Speed II.
- And, most of all, the Time Machine. After collecting a certain piece of junk, shooting a target will start a mode from a previous Williams title. Modes include "Mamushka", "Move Your Car", "Saucer Attack", and, in early revisions, "Payback Time".
- No Good Gofers has a few other references to previous Pat Lawlor tables, all of which occur when you lose all your balls in multiball without scoring the jackpot.
- Some of the ticker messages from Monopoly reference Pat Lawlor's earlier games.
"Become Lost in a Zone - Play Pinball.""The Electric Company keeps the Bank safe from Safe Crackers."
- One of the things Pin*Bot can say when you cheat in Jack*Bot is "Look, there's Rudy."
- In Johnny Mnemonic, shooting the outer loops several times in a row prompts Skull the Bone Head (from No Fear: Dangerous Sports) to appear and shout "Again!"
- During the Match Sequence for Scared Stiff, you can hear phrases from other Williams tables:
"Move your car!" (Creature from the Black Lagoon)
"A most beautiful princess..." (Tales of the Arabian Nights)
"Tell me more..." (WHO dunnit)
"The Earth is under attack... (Attack from Mars)
"It's a great day for racing!" (Indianapolis 500)
Weird singing (the little-known Williams redemption game Phantom Haus)
"Mother, please!" (from the 1988 Elvira movie)

- The globe on the backglass for Harlem Globetrotters On Tour includes a splotch of white paint next to Lake Michigan. Greg Freres painted the image during Chicago's notorious winter of 1979, and included that as a tribute.
- The Attract Mode for Sega Pinball's Mary Shelley's Frankenstein shows Sonic the Hedgehog alongside the Sega logo. After a few iterations, Sonic appears with big scars, like Frankenstein's other Creatures.
- In addition, on Starship Troopers, Sonic can also appear as one of the Brain Bug's thoughts during the Match Sequence.
- In Baywatch, after winning a Special on the Match Sequence, one of the random voice clips is Mitch saying "Never had a better day!" — a catchphrase of television series producer Gregory Bonann.
