Who Was the Mysterious Mr. X in Bob Zmuda's Book?

[SeveredNebula223]

In the book Andy Kaufman Revealed! , Bob Zmuda talks about a famous screenwriter that he worked as an assistant for. He refers to him as "Mr. X". This man was supposedly pretty psychotic. Who is he?

Was this man a real person, or was he another put on made up inside the mind of the famous put-on master mind Bob Zmuda?

If he is a real person, does anyone have info on him?

So it IS a mystery, huh?

It is unclear who exactly Mr. X is as Bob Zmuda has never revealed his true identity in the book or in any interviews. It is possible that he may have been a real person, but it is also possible that he was a character created by Zmuda for the purpose of the book. Without any concrete evidence or confirmation from Zmuda himself, it is difficult to determine the true identity of Mr. X. It is also worth considering that Zmuda may have intentionally kept his identity a secret to protect his privacy. As of now, there is no information available on the identity of Mr. X.
