Jonny Cronin- Is it required that performers have a specific form of knowledge?

No, performers do not require any formal schooling. While formal training may be advantageous, many well-known actors have never received a traditional acting education. Almost every actor working today, according to Jonny Cronin, has had some type of instruction. Actor training may take many forms, including workshops, BFA and MFA schools, on-set trainers, and even online classes. Which option is ideal for you is determined by a number of factors, including your age, level of experience, and whether you want to perform on stage or on screen.
