Oddly enough I was just (re)reading on the Mandela Effect the other day. Didn't run into the newer examples you mention, though. I swear I can hear Gandalf saying "Run, you fools". Checked with my son and he says it was "Fly, you fools". But then he was born many years after the movies came out so he may be of a different timeline...
I also refuse to believe Hannibal Lecter never said "Hello, Clarice"... wtf??
