Okay, so you're starting your script, and you have these amazing characters and you think you definitely think that Brad Pitt needs to act in this movie that you're writing. Don't put any descriptions of your characters with any references to actors, because it's not up to the writer. It's gonna be up to the director, and it's gonna be something that's pretty much between the director and the casting director. So don't write Tom, a tall, dashing, muscular type, just like Brad Pitt. Don't do that because it's not up to you.
