Speaking of which, Miharu (Kai's love interest) would also be Sango
In the English dub of the TV series, Mirai Yashima, Katz, Letz, and Kikka are all played by Spike!
In the English dub of the movies, Char was played by Steve Blum. When the TV series came to the West, it was on Toonami, hosted by Tom... who was voiced by Steve Blum!
Missing Episode: Episode 15, Kukuruz Doan's Island, was removed from the US release by request of Yoshiyuki Tomino himself. While most rumors claim it's due to the horrendous Off Model animation, Tomino himself said it was due to an issue between himself and a certain member of the staff, but he's not willing to elaborate any further as long as that other person is still alive. Note that this doesn't stop Doan from popping up in video games like G Generation and Extreme Vs..
Depending on whether Madman licenses by the series or franchise, this could be the case in Australia. Their staff seem to find it too dated to be worth releasing.
Bandai of America has had fun with this: the movie compilations are only available in Japanese with subtitles. Meanwhile, due to Bandai of Japan not wanting the US DVDs imported into Japan (where Mobile Suit Gundam had not come out yet on DVD) refusing to give Bandai of America the Japanese audio tracks, resulting in a English dub only release in the states. Only later did the series is get a bilingual release, though are now out-of-print.
For those not in the know, Amuro manages to destroy the Zakrello in about a minute. Afterwards Char says he's not bothered about the destruction of a suit he didn't even know existed.
What Could Have Been: The early preproduction notes and the planned 52 episode version include a lot of weird stuff that never made it into the final product, including:
The Gundam was originally going to be a somewhat less flashy-looking red and black robot with a blank, GM-like face called the Gunboy, but this was changed at Bandai's request into the more Toyetic samurai-like design we all know and love. The Guntank, by contrast, was much sillier looking, with its cannons sticking out of its chest and big, pipe-like arms with humanoid hands. Oddly enough, the Guncannon's early designs look about the same, except that it was supposed to be painted white.
Even after the Gundam's design was finalized its paintjob went through numerous revisions. The Zeon characters constantly referring to it as "The White Mobile Suit", despite a large portion of it being blue is an artifact of earlier script drafts that assumed Tomino's preferred color scheme of white with red highlights (the idea would seem to be resurrected in the far future with the Unicorn Gundam). There were also plans for an olive drab version known as the "Real Type" colors before pressure from the sponsors cemented the bright, primary colors of the finished product (which later sourcebooks explain away as "Demo" or "Parade Colors" intended to ensure maximum visibility when showing the new prototype's capabilities off to the brass).
Miharu was originally going to be a very different character, the only element surviving into the finished series being that she was still a redhead. In the original plot outline, Miharu Zabi was the youngest child of Degwin Zabi, a naive but sweet girl totally at odds with her warlike siblings. This version of the character was later retooled into Dozle's daughter, Princess Mineva in Zeta Gundam.
Char was supposed to pilot a Dom (which he does in the novelization instead of the Gelgoog, which was cut out) and even the Gundam itself in addition to the other suits he uses.
The battle of A Baoa Qu went quite a bit differently, featuring numerous new mobile suits that were eventually rolled into the MSV model kit line MSX (which at one point was going to become the basis for a proposed sequel before Zeta got made). The stand-out moment has to be when the Gundam is destroyed not in a final duel with Char, but by the MS-12 Gigan, Zeon's goofy response to the Guntank — and it wasn't even in the hands of a named character, to boot.
One major part of this would have included Degwin Zabi (who doesn't get killed by the Solar Ray in this version) breaking down in front of Sayla and begging her forgiveness for killing her father. The final version leaves the question of whether Zeon Deikun was assassinated or died of a heart attack more open-ended.
