I have never had trouble with any actor being able to visualise things. They are amazing. As long as you have your monster head on a long stick so you can hold it up there and you can wave it around and let them see it and explain it to them they are just great.
I can understand why some people might look at me and say 'What's she got to be depressed about?' I get that a lot in Britain where mental health issues seem to be a big taboo.
