I think that IMDb should have a category for principal but uncredited actors within each movies. The actor can provide a signed copy of the principal contract or residuals for proof. This new category (principal but uncredited) would be helpful to the actors and all entertainment professionals because it will show that the actor was hired for the project as a principal. As you know directors, agents, CDs, and managers use IMDb to check an actor's credentials. An uncredited designation does not accurately reflect an actor who was a principal but was not credited on the end credits.
