Note about the quiz!
Whilst the quiz is obviously just a bit of fun, there is a message here: you do need to be strict with yourself about editing. It might not be easy to cut some of your characters but your play really will benefit from tightening things up.
TIP: If you still find yourself lots of characters, think about how doubling might work. It might mean editing a few scenes so that the same actor can play one role, but this is worth it if you are looking to get your play produced.
