This isn't a mandela effect thing because I'm the only dumbass that remembers this wrong but i watched The Prestige in theatres and at some point my memory fucked up and swapped Christian Bale and Hugh Jackmans character up. I didn't realize this until I was talking about the movie like a decade after watching it and somebody told me how confused I was. Watching the trailer was a surreal experience because I had good recollection of each scene, but literally swapped the actors in them.
