Creator Backlash: Producer Jackie Marchand was not fond of the finished version of "Once A Ranger", which cut out scenes that would have made the Overdrive team's decision to leave explained better and made more sympathetic. She says the aired version "didn't reflect well on the Overdrive team and made them seem like assholes".
Dawson Casting: 18-year-old Rose was played by the then 28-year-old Rhoda Montemayor (though she looks very young for her age.)
Deleted Scene: There were deleted scenes from "Once A Ranger" which explained the Rangers' jealousy towards their predecessors.
Franchise Killer: While it didn't END the franchise, the failure of Operation Overdrive was the reason why Disney eventually gave up on the franchise and sold it back to Saban - the only reason the nexttwo series were made was because Jetix Europe and Bandai respectively asked for them to be made.
Screwed by the Network: Initially, when the premise of this show was pitched to Disney, the company actually liked the idea and greenlit the series...then suddenly did an about face and give the production staff a limited budget. Which forced the staff to use work arounds in order to produce the season, resulting in lackluster quality of the season. It was also by this point Disney was making it pretty clear they weren't interested in the franchise.
Talking to Himself: David Weatherley and Kelson Henderson double as the Fearcats' voice actors.
Troubled Production: In addition to Disney's budget cuts, the show was forced to make more Sentai footage-heavy episodes.
Samuell Benta (Will) wrote & submitted a theme song for the series which ultimately was never used.
Benta and Caitlin Murphy (Ronny) were supposedly invited to come back for Super Megaforce, but couldn't. Considering Benta's history with the franchise, it could be possible he was lying in order to rile up fans.
Apparently, Brandon Jay McLaren (Jack from SPD) was invited back for "Once A Ranger", but declined, wanting to avoid Working with the Ex (he and Emma Lahana had dated for a while, then broke up).
Working Title: The early working title for the series was Power Rangers Drive Force, but was later changed to Relic Hunters and then Operation Overdrive.
You Look Familiar: Subverted; Kelson Henderson returns yet again, as confirmed in the opening credits, but thanks to the Yeti suit and yet another vocal characterization (he's Norg), it's impossible to recognize him.
