Bit part
From Wikipedia, the free encyclopedia
A bit part is a supporting acting role with at least one line of dialogue. In British television, bit parts are referred to as under sixes (fewer than six spoken lines). Unlike extras, who do not speak any lines at all, actors in bit parts are typically listed in the credits. An exception to this practice is the cameo appearance, wherein a well-known actor (or other celebrity) appears in a bit part; it is not uncommon for such appearances to be uncredited.
Bit parts are often significant in the story line, sometimes pivotal, as in Jack Albertson's role as a postal worker in the 1947 feature film Miracle on 34th Street. Some characters with bit parts become well remembered. A good example is Boba Fett, with very few lines in The Empire Strikes Back and none (except a scream) in Return of the Jedi.
