The Cast Showoff: Antonio, portrayed by Glee alumnus Steven Skyler, gets a chance to show off his singing chops in "He's Not Heavy Metal, He's My Brother".
Power Rangers are certainly no strangers to acrobatics, but the show just wants to make it clear that Hector David (who plays Mike) is very good at backflips.
Christmas Rushed: A rare TV example. Production on the show was out rushed in 6 months instead of the usual year due to the timing of Saban buying the franchise back and trying to get it out at the usual premiere time of early the next year. It tends to show in that most of the early episodes are just recycled Shinkenger plots.
Executive Meddling: The main reason why this show was a Shot-for-Shot Remake of Samurai Sentai Shinkenger was due to Jonathan Tzachor believing that Shinkenger was a good show, and didn't want to change much of it, as noted here. The problem, however, was that Shinkenger was very heavily rooted in Japanese culturenote whether this was Toei retaliating in response to Disney wanting more control over the sentai to make it less violent, or due to RPM being the last season at the time Shinkenger began airing and Toei believing that Shinkenger wouldn't be adapted, thus they didn't have to take that into account when writing it, is unknown, to the point that prior to Samurai being announced, some fans believed that if Saban did get the rights back, they would outright skip Shinkengernote while this would've been problematic considering that if Saban adapted Kaizoku Sentai Gokaiger, which had Shinkenger used quite frequently, and one of the mech configurations came from Shinkenger, they could've explained it away in a similar way to the Alien rangers from MMPR using footage from the crossover between Shinkenger and Tensou Sentai Goseiger, which would've been the first season Saban had adapted if Shinkenger had been skipped.
It's worth noting that had Tzachor gotten his way, the rangers would've been sequestered even more, to the point where a proposal by one of the writers to have one of the rangers play with a Playstation was met with shock from Tzachor.
Fake Nationality: Steven Skyler, Antonio's actor, is not Latino at all. He's Thai/German and just happens to look kinda Latino. [It's especially funny because Hector David, Jr. (Mike the Green Ranger), really is Latino, though not Mexican (different sources claim he's either Puerto Rican or Cuban.)]
Additionally, despite being about Samurai and being the most Japan-centric season Rangers has ever done, Erika Fong (the Asian member of the team) is actually descended from a Korean mother and Chinese father. Eventually you have to wonder if maybe the ancient Samurai deliberately did this to protect their families and throw off the Nighlocks.
Many assumed that Deker was meant to be Japanese, giving how close the series was sticking to Shinkenger. However, this seems to have been averted, as his backstory has been altered.
May not have been averted. See Where the Hell Is Springfield? on the main page, plus there's the fact that Dayu refers to him as her brave samurai when they exchange wedding gifts, so either those two are Japanese or Samurai takes place in a world where samurai settled all over the world.
One of Us: With the exception of Steven Skyler (who said he didn't watch much TV at all as a kid,) all the Ranger actors have mentioned watching Power Rangers as kids and being fans when they were younger. Take that with a grain of salt, since a few sounded like they were being told what to say (and odds are pretty good at least one of them wouldn't have been)... with the exception of Hector David, Jr. (Mike), who's clearly getting the biggest thrill out of it.
Real Life Writes the Plot: The reason why Bulk's scenes are so limited, and he never interacts with the rangers (despite having done so multiple times at this point in the franchise) is due to Paul Schrier being unable to relocate to New Zealand - meaning that either they come up with an entirely new character, or they include him, but in a very limited way (they went with the latter).
Recursive Import: After Power Rangers S.P.D. and Power Rangers Mystic Force, this is the third PR series to be dubbed in Japanese since Saban got the ownership of the Power Rangers franchise back. And like in the case of the Mystic Force dub, regular voice actors are used instead of the original Japanese actors.
Screwed by the Network: Besides being underpromoted, as well as having to comply with Nickelodeon's "20 episodes per season" limit (resulting in the show having to produce a "second season"), the most recent hiatus during the Super Samurai season lasted for five months, during which time Nickelodeon Latin America already broadcast the final episodes.note As a result, they can't be advertised as "world premiere" episodes. There has been speculation that Nickelodeon may have been deliberately trying to get the show cancelled. This has mostly been disproven with Nick and Saban's latest deal to extend the series to 2016 with Power Rangers Dino Charge
Technology Marches On: The Rangers before the present group shown in a flashback are shown using Shinkenger-style Shodophone, complete with brushes, while the current generation uses laser-emitting ones. Highlighted much later, when Lauren appears and Mike specifically notices her morpher, inherited from her father, is different from the current set.
Troubled Production: A feature on Den of Geek with story editor James W. Bates confirmed that Jonathan Tzachor was responsible for the extensive rewrites of fifteen episodes to make it a carbon copy of Shinkenger.
According to a recent interview, during the audition process, at one point, they moved Hector David, Jr. over to the Gold Ranger.
Originally Amit Bhaumik proposed that this series was to take place in Stone Canyon and Mia would be a relative of Cassie but Jonathan Tzachor decided not to go with this idea.
As it turns out, there's quite a lot of ideas Bhaumik had that were rejected, as this Tumblr post reveals. A few details that stand out:
The Red Samurai Ranger was going to be a Japanese-American young man named Mark Ozawa, descendent of a long line of samurai who fought against the Ashura Clan. His main rival would be a young man named Keiji Ayakawa, who would be revealed early on to be a descendent of Master Xandred, who in this version was defeated and petrified as a statue. Xandred would return, however, serving as the show's Bigger Bad. Keiji, jealous of Mark's samurai legacy, would readily join the Ashura Clan, as well as have the ability to transform into a demon (this would be Juzo's counterpart).
The other four Rangers would hail from different countries, such as Austria, Nigeria, the UK, and Mexico.
Bulk would have a larger role, running a sushi restaurant the Rangers would hang out in. Along with his nephew, Eugene (a prototype for Spike), they would help the Rangers, similar to the kuroko.
Eugene would eventually become the Gold Ranger, creating his own morpher behind the others' backs.
The Ashura Clan operated from the Dread Castle, a demonic version of the Osaka Castle in Japan. The Moogers were originally called "Marauders," and Akumaro/Serrator would originally be a mystic who betrayed the Red Ranger's family, resurrected by Octoroo (here named "Octomancer") as a demon.
Mark would hand over the title of Red Ranger to his cousin Alison (Kaoru's counterpart) when it is discovered that he is actually a descendent of the Ashura Clan.
Really, there's a lot of information. Check out the link above for a massive case of What Could Have Been.
Emily was almost played by Ciara Hanna, they even had the contract ready, but she backed out before signing. She would return to play Gia in Power Rangers Megaforce.
According to James W. Bates, "Clash of the Red Rangers" was originally going to be 75 minutes long and that the other RPM Rangers was going to appear and interacting with the Samurai Rangers, though like Scott, they would remain in morphed mode and would be voiced by their actors instead due to actor unavailability. In fact, the infamous line "Your team says hi" is in a fact a nod to that deleted scene.
Word of Saint Paul: Hector David Jr. has said that his character's last name is "Jackson" in an interview with The Hashtag Show. However, no in-show evidence or related material states this.
