Can't remove a credit from my imdb page however how many times I try

IMDb documents on screen credits. Even if there was a mistake.

Does IMDB verify the on screen credits by viewing footage and  if so may I have access to the footage? As a SAG-AFTRA actress of 22 years I find it disturbing that a signatory producer whom is obligated by SAG to the fair treatment of SAG actors put any credits they want and there be no recourse.  I have created  goodwill in my field and don't want to be portrayed incorrectly to my piers.  After all IMDB is a big calling card to many possibilities I have earned and I don't want them to be denigrated.

Yes.  They verify by looking at footage or screen captures.  That's exactly what you'd need.  I wonder why that was not your question, though.  IMDb doesn't consider any of what you've described but documents what's on film.

Notice, for example, the cast/crew for Annie Hall.  There are many mistakes such as Christopher Walken's name being misspelled.

So, if your real question is, "I got credited wrong on IMDb and have the on screen credits to prove it," the answer is, you'd click "edit page" for that title, choose to correct cast, enter the correction and supply a screen capture of the credit and ask they change it.  None of the "SAG" issues are relevant. Just upload an image of the screen capture here (well, not here but open your own topic and don't attach it here where it doesn't belong) along with the Submission ID that gets generated. Or upload it to a pic hosting site, or dropbox.com or box.com folder, then add it in the "explanation" field during the submission. Staff will review it.

Got it.  Thanks for clarifying.  I do not however have access to the footage so I could not verify.  Knowing IMDB does look at the footage answers the question though. 

You're very welcome!
