Other mistake: During the first phase of the battle with the Zeon forces, in particular in close-up when Amuro botches the landing from the catapult and drags the mobile suit belly down onto the rocks, the V shaped head ornament is entirely red, instead of being red in the middle section and white in the fins. (00:15:40)
Continuity mistake: Bright is sitting in his quarters, exhausted. Mirai enters his room, and he zips his uniform up; it is specifically shown that the zipper goes past the undershirt. When Sayla sends the alert from the bridge, Bright jumps up and answers with the tank top showing. (00:07:00)
Other mistake: The three comic relief kids burst into the bridge with hoover. The floor they are cleaning is a single smooth surface, but when Bright apologizes to them, they are standing on the only section with tiles. (00:06:40)
Continuity mistake: Amuro gets up from the floor when he's been working on the Gundam backup computer. Going by the floor boards, the manual and the trays with the tools have moved around between shots. (00:05:45)
