Creator Backlash: Tomino has a special kind of hatred for Episode 15: Kukuruz Doan's Island and refused to let Bandai America dub it or release it locally. Ironically, while the animation quality of episode 15 is poor, many fans consider the previous episode Time, Be Still to be far worse in the writing department. This is ironic because the script for episode 14 was written by none other than Tomino himself.
Hey, It's That Voice!: Being the second Gundam dub done by the Vancouver voice pool, and produced by The Ocean Group, there's plenty of overlap with previous and future Gundam dubs.
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. 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). One of these, the Guntank-like MS-12 Gigan, piloted by a nameless grunt, was supposed to have killed Amuro because Tomino didn't want to make any sequels. Despite this rather radical move, the finale would have progressed more like a typical action series from this point on, with a dramatic final showdown where the protagonists confront the remaining Zabis in person.
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.
