What tests and exams do you have to take to be a actor?

Unless you're a famous actor who they write parts specifically for, actors get roles through a series of interviews and auditions. These can be really short and simple or weeks-long ordeals consisting of speaking with the director and producer, acting scenes you'll be in with other people in that scene, costume and makeup tests...the bigger the role and the more expensive the show, the harder the audition is going to be.
