A while back I did the fight choreography for Richard III. On this page you can see some pictures from this choreography.
It also lists me as the understudy for the Duke Clarence. About two weeks before the performance date, I was rehearsing the fights with the actors, and the director asked me to do this role. Luckily, I had studied Clarence’s key speech (“O, I have pass’d a miserable night…”) at AMDA. So I was able to jump into the role with one rehearsal (which was not with the actors, by the way). It was a little harrowing, but the actors did a good job of working around me. In particular, I remember doing the scene with the murderers and having no clue what their blocking was. At one point, I stood up and crossed, which was evidently not correct because one of the actors gently (but in a threatening manner, very much in character) grabbed my arm and led me back to the seat.
Another site which reviews another play I did choreography for gives me the glowing compliment of “There is good fight choreography by Stephen Heskett”.
