You might be on a sitcom working with other actors and actresses to make people laugh, or you might do a small modern performance giving monologues by yourself.Even more varied are the roles you portray. Just like any of your favorite movie stars, you might spend six months on a movie playing a famous pilot from history, and then on your next job play the villain in a futuristic world. Who you’re supposed to be will change with where you’re working, so you need to make sure you get the training you need to keep up with your role’s demands.
