Undeserved credits can't be removed.
I am the Exec Prod of the HBO special Lady Day at Emerson's Bar & Grill that starred Audra McDonald. She just received an Emmy nomination for her performance in this one woman show this week. Some months ago I noticed that two of the extras we had in the audience seemed to have given themselves unscripted and uncredited roles and added themselves at "cast members: of this one-woman show. This is inappropriate and unfair and I have twice tried to remove their names from the IMDB listing. IMDB neither removes their names or responds to me so I am writing this here. I think that those two cheaters should have their names removed or, if not, then IMDB should institute a policy that everyone in the audience of a performance taped for television should be entitled to a credit. In this case, since there were 54 people in each of the 3 shows we taped, we could have 150 cast credits for this one-person show. Don't know what to do next.
