Double Cross - S3-E2
Visible crew/equipment: When the Professor returns from the vortex and punches the guard, in the guard's glasses is the reflection a crew man holding a boom in his hands. Look closely in the right lens. (00:39:05)
The Young And The Relentless - S2-E11
Visible crew/equipment: When Q notices a body face down in the pool, the camera points to pool and pans right. You can see a female crew member at a table with papers in the reflection of the glass door/window. (00:00:50)
Greatfellas - S2-E10
Deliberate mistake: When Quinn comes back to the hotel room with a large stack of money he'd won at the casino, he waves it, and you can see a 1-dollar bill in the middle. He was supposed to have over $100,000, but since the crew couldn't get that much money for a brief scene, they used a stack of dollar bills. (00:35:40)
Quinn Michael Mallory: We have a plan. We just don't know what it is yet.
Trivia: The man who is homeless in "our" world, and is running for the U.S. Senator in the parallel universe, is the episode's director, Andy Tennant, making a memorable cameo appearance.
Suggested correction: The homeless man (Crazy Kenny) was played by Frank C. Turner, not Andy Tennant.
Question: In the pilot episode, the wormhole physically travels to "capture" Quinn and bring him back to his own world, after his very first slide. How did the wormhole know where Quinn was?
Chosen answer: Remember at first Quinn's timer is working perfectly (it's only because they slide off the ice age world early that it begins to malfunction) & given Quinn's intellect he would have devised a way that he could open a wormhole near him so he wouldn't be trapped on that world for 29 years.
