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)
Sliders (1995)
1 visible crew/equipment mistake in season 3 - chronological order
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)
Just Say Yes - S4-E7
Agent Lowell: That's Mallory all right. Busted twice for non-possession. Jumped bail a year ago and ran off to Mexico.
Damon: I heard he died of an under-dose.
Agent Lowell: Same here. I guess we were wrong, huh? It's a safe bet Mallory snuck back into the country to spread more of his anti-drug propaganda. A guy like that shouldn't be on the street.
Trivia: On the equation on Quinn's chalkboard, T squared ("T2") appears in several places, a nod to Tracey Torme, Co-director of the series.
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.
