 SPOILER: The films most famous line is often misquoted. While many  believe that Darth Vader says; "Luke, I am your father." He actually  says; "No, I am your father." Even James Earl Jones (qv), who  provided the voice for Darth Vader, misquoted the line when  referring to it on the  _Empire of Dreams: The Story of the Star Wars Trilogy (2004) (TV)_ (qv)  documentary. The misconception probably came about as the result of  the fact that in the comic book adaptation of THE EMPIRE STRIKES  BACK, Vader tells Luke: "No, Luke. I AM your father."
