Some people are able to break into the acting world without any qualifications, or by transferring from a related profession such as being a musician, or having a lucky break from amateur acting, but the majority of actors have studied at a drama or stage school. There are many different courses run at the various colleges, and these may be one, two or three year courses, some of which will lead to a degree in Drama or Theatre Arts, etc. Most applicants for courses will need to pass an audition. Courses are run for applicants at stage schools at any age from five upwards, and it is possible for people to enter acting at almost any age.
