Iam 18 years old want to become a bollywood actor what should i join theatre or film academy

In fact both, Theatre will give you experience and at a film academy you will learn the essentials and technical aspects. Brush up your skills frequently. Remember, not all actors have passed out of a film academy.

You get your training with the help of a good institution nearby. You will find that TV is the main source for exposure and you will receive experience by acting in films.
