Although John Rhys-Davies is credited with this episode's story, his idea is remarkably different than what made it to screen. Davies's treatment would have been about a world where the comet Shoemaker-Levy 9's impact with Jupiter would have altered its orbit, the result being gravitational shifts that send Earth to slowly drift away from the Sun. The issues of the timer revolved around Quinn and Arturo discovering that with some modification with parts from a Motorola factory they could fix the timer to take them home since the story would feature Quinn's original timer and not the new Egyptian one. But it could also be modified further to transport what remains of the Earth's population to a new world. If they did, the timer would burn out from the stress and resume its random sliding status. The moral dilemma set in the story is that some people want to leave others behind so that they can take more of their own possessions.
The establishing shot of a building referenced as Caltech by the Sliders is acutally the Valley Life Sciences building at UC Berkeley.
Rickman: (referring to sliding) I never spoke with the President.
Rickman: All we'd end up doing would be taking his friends, politicians; people with no usable skills, no value to anyone.
Quinn: Nothing like an air raid to bring out the looters.
Quinn: (to Maggie) Sorry, he was bleeding too loud.
Wade: (referring to Maggie) There's something about that girl that I don't like. No. Make that everything about that girl I don't like.
Quinn: (referring to Maggie) Ah, yes. The big, tough fighter pilot. I can hear your brass clinging.
Quinn: (quietly; to Professor Arturo about travelling with Maggie) It's like sliding with Patton.
The physics of the pulsars depicted in this episode (and its second half) are incredibly unrealistic. For starters, a pulsar is, as Arturo describes at one point, a star that has collapsed in on itself. Not only would it be spherical in shape, but its density would cause so much gravitational havoc before it even entered the solar system, that it would knock planets out of their orbits.
The gun Wade points at Maggie appears to actually be aimed just to the left of Maggie.
What did the sliders do with the guards that accompany Maggie after they lock her in the trunk of the car? And why are they walking away from the scene so calmly afterwards?
Why would an Englishman be in charge of the United States military?
Jensen explains to Quinn that he is parapalegic because he severed a neurotransmitter. That is physically impossible since a neurotransmitter is a chemical.
Arturo says that they will slide out on the world they transport the endangered world's people to. However, it's been established in the show's mythology that a gateway can only be opened on the same world they slide into because the timer is counting down to the next accessible window on the world it has brought them to. While a castrophe of enormous proportions could quite possibly make sliding out on the same world difficult, nothing is made of this.
