There are about forty-two characters in Henry V; I'm up for it, but we'd need a lot of recruitment. If we're doing it by voice-acting without graphics, having one person per part is pretty vital. The Tempest has about twenty people needed, and Othello a similar number.
We could double up if we had a decent way of doing graphics, but filming the shots for The Teacher in AOEIII took ages and looked hellish so we'd need a much better method.
