THE MANDELA EFFECT Trailer Questions What We Think We Know

What do you only think you remember?

If you're unfamiliar with the Mandela Effect, it's this psychosocial phenomenon where people collectively remember an event that didn't happen or differently than how it actually happened. The colloquial name for this kind of false memory stems from how many people falsely believed that South African leader Nelson Mandela had died in the 1980s, but other notable examples include people remembering the Berenstain Bears book series as the Berenstein Bears, or that Sinbad starred in a movie about a genie called Shazaam. These are minor things that have rational explanations for why we believe them, but the realization that you misremembered something so clearly is disconcerting to say the least.

So naturally some folks made a psychological thriller about it.

Yeah, I'll totally watch that.

The Mandela Effect premieres at the Other Worlds Film Festival in Austin on October 23, before getting a theatrical release on December 6. But dear BMD readers, we want to know: what's your take - or double-take - on this movie? Sound off with your favorite collective false memories in the comments section.
