A cast member is:
- An actor, dancer, or singer who performs (i.e., sings, dances, acts, mimes, puppeteers, voices characters, etc.) in a theatrical production, motion picture, or television program. The actors who perform in the show are collectively referred to as the cast.
- Any employee of the various Disney theme parks, including the original Disneyland Park in Anaheim, California and the Walt Disney World Resort. Other Disney parks and resorts around the world also use similar terminology. Employees of Disney Store locations are also referred to as cast members. This terminology is derived from Walt Disney's use of theatrical analogies when referring to park operations.
