This is the only Power Rangers series, to date, to be nominated for an Emmy.
Jen makes a Power Rangers first, by using the word 'death', when, she says, "I won't let his death be in vain!"
Eric was originally slated to die, just like his counterpart in Timeranger. The writers were skeptical that Fox Kids would allow this, so they filmed two versions of the scene: one where he died, and one where he lived. Fox Kids, as expected, vetoed the death.
In "Trust and Triumph", a line by Circuit, announcing a "Mutant at the Trade Center!" was changed to "Mutant at the Industrial Center!" after the September 11th attacks.
