A-list actors are those whose names are still so relevant and famous and still making box office hits that they do not need to audition for parts and often have parts expressly written for them. In order to remain on the A-list, an actor must take mostly starring roles, do well at the box office, get good press, and remain relevant to current audiences.

B-listers are those who have not had recent hits but are still very well known and have fans and followings. They often include teen idols and people who used to play starring roles but now play supporting roles due to age or lack of relevancy.

C-list actors are those who everyone recognizes when they see their faces on screen but no one really remembers their names. They are hard workers who get plenty of work, but are not famous in terms of instant public recognition nor do they get starring roles.

D-listers are those who are often very talented but either don’t land many good roles or are such stylized characters they are often unknown in their own right. This group also includes the up and comers who are just getting started or who have been at it for a while, but haven’t had many breaks. Casting directors often refer to this list when looking for a great actor to do a small role that means a lot to the plot but won’t get much attention for the actor.
