Rotating Camera Animation Guide

Annotations complete! Well, not really a useful thing to know how to do a rotating run cycle on the spot, but a few people wanted to know how this was done for Bravehearts Legend intro sequence and i thought it might be a good way to show how to animate using Key frames and in-betweens as an alternative to straight-forward animation eh. Though i use a run in this, it could be used for anything and helps you visualise a character in 3d too. Need reference from live animals?
