Trivia: When Silver Surfer witnesses a galaxy moving backwards through time, he refers to it as the Kirby-Lee quadrant. A reference to Marvel Comics legends Jack Kirby and Stan Lee.
Trivia: Mike Pratt (playing Jeff Randall) really was laid up in a hospital bed with two broken legs. Mike Pratt was attempting to climb a drainpipe in a slightly inebriated state during his 38th birthday celebrations. He fell 20 feet into the basement area. He'd forgotten his keys, and saw the stand-in doing it - successfully - first. Mike being Mike, he thought, "I can do that" and had a go. Jeff's 'in character' excuse in the show was that he'd fallen from a balcony in a chase - a little more dignified than the truth.

Trivia: Only mentioned in one episode early in the series, Steve Austin's least-referenced superhuman power was his ability to hold his breath for extraordinary lengths of time. Steve's phenomenal breath-holding ability was due to the fact that, even though he had two normal lungs, he had a much smaller circulatory system than a normal human being. Also, the Steve Austin in Martin Caidin's original book, "Cyborg," had an entire array of weapons, flares, communications gear, retractable swim fins, and scuba tanks built into his bionic body.
Trivia: The animated series featured the first appearance of the Holodeck (called the Rec Room) in this episode only. Gene Roddenberry wanted to use the Rec Room/Holodeck idea in the original live action series of the 1960s, but found that budgetary constraints were prohibitive at that time. The Rec Room finally appeared once in the animated series, in this episode, in 1973. It wouldn't be seen again until Star Trek: The Next Generation, in 1987, some 14 years later.
