This topic was first raised in August 2015, around the time that the Berenstein/Berenstain topic surged in popularity. So, it may have become lost in the Bears discussions.
David S. was the one who mentioned it. He said, “I’ve noticed weird examples of this for years. E.g. a movie with Sinbad where he plays a genie but the closest thing would be Kazaam with Shaq.”
David S. was correct, in a 2014 Q&A Interviewly.com session, here’s what Sinbad said:
Sinbad, there is a large rumor/conspiracy going around that you played a genie in a movie in the 90’s similar to Shaq in Kazaam. Can you confirm or deny the existence of this supposed film? Thanks for the AMA!
it was SHAQ SHAQ SHAQ
but we all look alike
Several people replied to David’s comment, and I’ve moved their comments to this post, focusing specifically on the Sinbad movie.
Since I saw the movie in search results — and images from the movie, as well — when David S. commented (August 2015), I’m not sure the timing matches. If anyone else has both memories and can give a time frame, that could be useful.
Sinbad looks like a genie. To me, it’s not just the missing movie that’s odd… it’s that, in this reality, no one cast him as a genie, ever. It’s hard to imagine Hollywood not making good use of obvious casting and easy marketing.
UPDATE: This seems to be the same alternate memory being discussed in December 2016 as “Shazaam.” http://www.newstatesman.com/science-tech/internet/2016/12/movie-doesn-t-exist-and-redditors-who-think-it-does
