As actors, we can play any character that there possibly is but the likelihood of us being cast for those roles is a different story. It is very important for everyone to know their character type. (I have trouble with this myself) Your character type is a kind of character that you can believably play on camera. Lets face it, I can not be cast for a film that is looking for an 80 year old Asian super villain. I can not play 80 or Asian with out some type of make up or special effects. What are 5 characters or character types you can easily see me play and audition for? I encourage you to do the same. It would help hone our skills on finding a monologue tailored to our character type.
There is a slippery slope between character types and stereotypes. I do not agree with stereotypes in films.
