no, it's not easy at all. there are lots and lots of people who go there every day to try to get parts in movies and shows and never get anywhere because there are so many people trying for the same part. do you have any experience? do you have any training? people spend their whole lives acting, waiting for that "big break" and never get it. you need to either have lots of money to live on or be able to get another job to support you while you go for auditions.
dont waste your time get a real job because actors and actresses arnet people when you move to hollywood you lose your sole and become a actor but serioiusly other you need to be a good actor to make millions
