I posted this question yesterday but I cannot see the thread so here I go again.
My brother claims that the line by Darth Vader "Luke, I am your father" has now changed to "No, I am your father".
My brother claims that due to the Hadron Collider experiments, some things such as lines in movies, cartoons etc have miraculously totally changed from what they used to be. He said this is called the Mandela effect.
My brother said everyone knows the line in the first Star Wars movie was "Luke, I am now your father" but has changed to "No, I am your father" and nobody can explain it?
I just want to know..... has the line changed...if so, .is it because the latest version has been remastered or something".
I think he is talking crazy so I thought who better to ask than some die hard Star Wars fans.
