Dawson Casting: Par for the course in any Power Rangers cast, but this series has one of the most egregious examples with Melody Perkins (Astronema/ Karone) being 4 years older than Christopher Khayman Lee, yet playing his character's younger sister. It's also worth noting that Melody and Christopher are respectively the oldest and youngest out of all of the In Space cast members—Melody was born in 1974; Chris, in 1978. Everyone else was born between 1975 and 1977.
Dyeing for Your Art: Christopher Khayman Lee — the cartoony, sci-fi skunk stripes in his hair were not his idea. At first, they told him he was going to wear a wig; but then, when he came to L.A. the crew were basically like, "Surprise! We`re going to bleach your hair now!" It was painful to say the least; in fact, it took at least 8 hours to get it just right, and with his head feeling like it was on fire on top of that. Even worse, his hair grew so fast which meant his roots began to show in his streaks... meaning that they had to touch-up those roots with the bleach each time, yikes! In this Q&A video posted on his YouTube channel, at around the 7:28-minute mark he answers a fan's question about whether or not he would sport the Andros-'do again (he said no) and he continues to talk about it for another 3 minutes or so. In spite of it, he still enjoyed his time on the show regardless.
When he made his appearance in the 10th anniversary special, "Forever Red", he did not want to go through the bleaching process again so they gave him a wig.
Enforced Method Acting: On Christopher Khayman Lee's first day on set, he was pulled aside by Jonathan Tzachor and was told to act like an asshole to his castmates and to avoid them off-screen so that Lee could get into full character as Andros, much to Lee's chagrin. So when you see Andros eventually warming up to the rest of the Space Rangers, you'll know why.
Musical Nod: The music used for Carlos's Training Montage in " Always a Chance" is the same as that used in his debut scene is Turbo's "A Drive to Win."
What Could Have Been: A pre-series bible shows that they had intentions of retaining Justin (IE. no Andros). The Bigger Bad from Carranger, Emperor Exhaus, would be used as Dark Specter, as opposed to recycling the Maligore suit and using Exhaus for Turbo'sGiant Space Flea from Nowhere, Goldgoyle. Divatox would stay on as the main villain, the Mooks from Megaranger would be used instead of the American created Quantrons, Darkonda was to be named Spike, and Bulk and Skull were going to start a Civil Defense Force with the Rangers away.
Rita, Zedd and Divatox were supposed to die in the finale because of the Z-Wave. However, the Fox Kids censors did not like this, so they were spared.
The Phantom Ranger was originally going to have his origin revealed during the finale, but these scenes were cut when Fox cut the finale from three parts to two.
Christopher Khayman Lee's sister Chyler Leigh was considered for the role of Astronema. Had this happened, then the Real-Life Relative trope would come into play.
All the stranger when you consider Maligore was a demon the size of a Megazord at his biggest and Dark Specter is the size of an entire PLANET. He's also seen to shapeshift, which makes you wonder why he picked someone so many magnitudes of power weaker than himself to impersonate. Probably because Maligore looks scary. Besides, maybe they're related.
In an early draft of "Forever Red," Amit Bhaumik had proposed the idea that Maligore was an infantile version of the species that Dark Specter was a part of. Since this never made it to the final draft, it's anyone's guess how canon that idea is. On one hand, it would explain the similarity between Maligore and Dark Spectre. On the other, the fact that Maligore is technically an infant version of the species and that Divatox was his girlfriend... well, the implications are not pleasant.
