Just sharing more I've discovered by turning on the Storyboard feature as the film is playing. You get to see (very) rough sketches of the scenes as they unfold in the film. Anytime all the rabbits are in a group shot, they would often be labeled with the letter of their first name so you know which rabbit was where in the picture. The dialog that was fitted to the scene was put underneath.
A couple of things you wouldn't know unless you watched this:
- the dialog on the storyboard does not always match what actually ended up in the film, so takes and re-takes must've occurred a bit, most of it matches perfectly
- Fiver was supposed to have dialog as the group climbs up the down; he was describing what it would be like on the down--can't recall if this is in the book anywhere. Anyway, the final film has none of this dialog, and only the score which is the much MUCH better choice!

It would take away from all the power of the music if that dialog remained.
- the Bright Eyes sequence was originally going to use the pop-version of the song. The lyrics to the second part of Bright Eyes were sequenced in on the storyboard after the pipe with the blood fell out in front of Fiver. This was all replaced with the instrumental interlude from Angela Morley with only a slight reprise of the main lyric, "Bright Eyes burning like fire...."
- during the scene where Hyzenthlay was talking to Woundwort about starting a warren somewhere else, the scene where the does go into burrows and then a male rabbit follows, it was really captioned on the storyboard as a "rabbit brothel"
