I was tipped off early that this tale was imaginary when the segment mentioned Brooks’ “The History of the World, Part I” among the Brooks-Korman collaborations before telling the tale of the friction during “High Anxiety.” That film was made four years after “High Anxiety.” Then, as the segment drew to a close, I remembered that Korman also had a substantial role in an even later Brooks-directed film, his Dracula satire, “Dracula: Dead and Loving It” which rolled out to tepid reviews 28 years after “High Anxiety.”
What I didn’t know was that in 1989, twelve years after Mel supposedly never worked with Harvey again, Brooks produced a TV series starring Korman, “The Nutt House,” one of two doomed American efforts to duplicate the hilarious John Cleese sitcom, “Fawlty Towers.”
In short, the “Studio Tale” that Mel Brooks found Harvey Korman so difficult to work with that he blacklisted Harvey after “High Anxiety” is completely false. Furthermore, there is no excuse for it: a simple search in the Internet Movie Database, Wikipedia or other sources would have revealed the truth in seconds. The fake “Studio Tale” isn’t just a mistake, it is signature significance for a lazy, reckless, irresponsible and dishonest content creator. That segment means that nothing claimed on the Studio Tales YouTube channel can be trusted, because even perfunctory research fact-checking isn’t part of its process.
Putting that kind of false information on the web is unethical, and personally, I detest it with the flaming fever of One Thousand Hells. This example is unfair to the public, but also to Mel Brooks and the late Harvey Korman.

I listened to a random tale for about 20 seconds. I am pretty sure the voice is A.I. It is likely some overseas content farm producing low effort slop and hiding behind the seemingly respectable voice of a British gentleman.
Also, it tries to cover its digital butt with a catchall disclaimer hidden down in the netherworld that is the video description:
1. ARRGH! I am abashed! I never considered AI…and I know I have to consider it all the time now.
2. What a ridiculous disclaimer. They obviously don’t aim to present these tales as accurately as possible, because nobody checks the facts.
Yep, AI slop. The voice is AI and the writing is AI.
“The Nutt House” is available on YouTube. I was disappointed in it because I felt it should have been funnier with both Korman and Cloris Leachman as the leads.
Carol Burnett had friction with Korman, too, but it was worked out. Apparently, he was a bit of a perfectionist.
The other “Fawlty Towers” rip-off starred Bea Arthur, and it was no better. It like the episode in “Mad Men” where the client wanted a TV ad using an Ann-Margret type doing a parody of her famous opening to “Bye-Bye Birdie.” The client sees the finished product and rejects it. The “Mad Men” are confused. “why didn’t they like it? the actress did a great job!” “She isn’t Ann-Margret,” a partner says with a shrug. Harvey and Bea were really good, but neither was a John Cleese.
I vaguely remember Bea Arthur’s show. Wasn’t it called, “Amanda’s” or something like that?
