What I want to know is this. What can I feasibly have go wrong, on stage and backstage, that will annoy and stress out the cast and crew but that won't stop the performance or hugely affect the audience? I've read the Wikipedia entries on stagecraft and related, and on the Dream, but right now I'm out of bright ideas, and would be interested in personal anecdotes, if anyone has them - I'm looking to get beyond the obvious forgetting-of-lines, although that will, of course, happen. :)
In addition, I really would like to finish with my director getting knocked out. If it were an ordinary production I'd have someone drop a flat on his head, but that's not possible outdoors, is it? How else can I get the poor guy concussed? *g* Many thanks.
Edited to add: This is so great, thank you. (And quite apart from my query, the comments are a great read. :P)
