Out of respect to writers you have to read the book in the way in which the author visualised it going out into the world.
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.
Something I didn't even know was on my bucket list has been achieved. I have cooked Thanksgiving dinner with Martha Stewart. I vow to follow the gospel of her teachings and do my very best in the remarkably less glamorous kitchen of my own home... without the luxury of magically appearing prep bowls filled by a staff of sous chefs.
