How would you feel if you could no longer trust your own memories?

Director David Guy Levy is exploring a fascinating phenomenon in his upcoming sci-fi film The Mandela Effect, wherein a man becomes obsessed with facts and events that have been collectively misremembered by thousands of people. Believing the phenomena to be the symptom of something larger, his obsession eventually leads him to question reality itself.

Check out the mind-bending trailer below, which plays around with several well-known examples of the “Mandela Effect” and promises an unsettling take on the phenomenon.

Charlie Hofheimer stars alongside Aleksa Palladino and Robin Lord Taylor.

The film will be released In Theaters and on VOD on December 6, 2019.
