Actors and actresses perform, creating new worlds on the stage or in front of a camera. Actors and actresses can be the celebrities you see walking the red carpet at the Oscars, or the people who perform in a small independent play at a community center. For this job you have a lot of different work environments, and no two will be the same. 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.
