Sinbad should just go ahead and make that movie now. He can then release it with a marketing campaign that says, "The classic childhood favorite, lost for 20 years, now available and fully remastered!"

I think I have a valid argument for this theory besides people mistaking this with Shaquille O'Neal's 'Kazaam'. In an episode of Nickelodeon's 'All That', Sinbad once played the father of Ishboo (played by Kenan Thompson) 'Sinboo'. And I recall his clothing being very similar to that of a Genie. Can enough people be mistakenly conflating their childhood memories of Sinboo and Kazaam and creating 'Shazaam'..?

Also there was a TV show called Shazam.

A Mandela effect that stuck with me was that North/South Korea were detached islands a bit south of Japan, but detached from China.

That and the fact the US has 52 states not 50

It’s only a Mandela effect if many people share the memory.

The "52 states" thing seems to be a common false memory: http://www.debunkingmandelaeffects.com/51-or-52-states-in-th...

Personally I also remember (as a child) thinking that the US had 52 states but that's mostly because "51st state" is a common expression I likely came across frequently enough to think that there are at least 51 states, 50 feeling too rounded and 52 being a close enough number that frequently pops up elsewhere (52 cards in a deck, weeks in a year).

I don't like the term "Mandela effect" because of the pseudo-scientific connotations, though. It's just a false memory and in many cases it's not even a memory, just a misconception (like thinking there are penguins at the North Pole because it's easy to mix up the Arctic and Antarctic or to mistake puffins for some kind of penguin).

EDIT: As for Korea: googling yields several claims of people misremembering its placement on the map but if I had to guess I'd blame news reports that like to highlight countries on the map by showing them in isolation or exaggerating their borders by creating a small gap around them.

Also the fact most US maps show Alaska and Hawaii semi-separately makes me think its 50 plus 2.

Also DC not being a state as well as all the "territories". I'm pretty sure I as a child I thought DC counted as a state.
