1. extras- used to add in a sense of a crowd, so its not just the main actors. they usually don’t have any lines.
  2. nonprofessional performers- not professional or particularly good at acting but they look like the characterization of the part.
  3. trained professionals- actors and actresses that can play many different roles in film
  4. stars- well known performers that most people know and can recognize, usually they are good actors.

Stage acting- stage actors need to be genuine in their part and believable, even if the part seems to be foolish. they must always be seen and have to take credit for all the acting.

Screen acting- an actor in movies and videos. not as much of a responsibility as a stage actor because it is not all live action and a straight show. There are cuts and edits in this acting.
