Let me me mention this again,
That Zeon mark on the podium doesn't seem to be something Tomino made up for this board. There are settei of 3 different Zeon marks. One of them seems to be this mark that Tomino used here.
Final version replaces it with an eagle.
There is also this short scene from the storyboard that is placed right after Char and Nanai's scene (48:34.) It shows Amuro using his psychommu headset a bit more (which is connected into the psychoframe monitor.)
Another extra scene in the storyboard that seems to have been cut. It happens right after Char climbs down the stairs of the podium after his speech (52:09.) He also takes off his cape (which he doesn't do in the final version.)
The actual bite in the film goes by in a split second.
