Actresses and actors are performers who portray characters in productions, including those for stage, television, motion pictures, radio, and even theme parks and cabarets. As an actress or actor, you might perform research to help you better understand and embody a character’s circumstances or traits, especially when preparing for a complex role. Acting is an intensely competitive field, and it may be difficult to achieve recognition or get steady work as an actress or actor. Few who try to make it in this field become big movie stars; instead, you might work as an extra, a role that generally requires listing by a casting agency and often has no lines to deliver.
