A few weeks ago, Tracy Mark Lee revealed that Mel Brooks was originally planned to be in an episode of Scooby-Doo and Guess Who? that was scrapped. Now, Tracy has just posted the character design for Mel Brooks on his Instagram page designed by Stephen Silver, which can be seen above. I had also speculated in my previous post that perhaps Mel Brooks (and Dolly Parton) could have been substituted out of the episode for another guest star. However, Tracy has confirmed that this did not happen any other other case except with the Hex Girls episode, which KISS was originally supposed to guest star in, but they were scrapped as guest stars at the last minute after the episode had been nearly finished. He went on to explain that the episodes were always based on the guest star's background and history, so that the episodes would be more personal. The Mel Brooks episode was scrapped quickly, so very few aspects of the episode were developed.
