Doc Brown: What is it, Einie? Oh my god, the found me, I don't know how, but they found me. Run for it Marty! Marty: Who, who?! Doc Brown: Who do you think?! The libyans!!!
Ernest Borgnine .
He, at first, lives in 1985. Then, he travels back to 1955. I know, this is an old movie! Then, in the second movie, he travels to 2015. I don't know where they go in the third movie.
When Marty first travels into the past, Doc has the car set to November 5, 1955. When Doc tells Marty and Jennifer to come with him "back to the future" at the end of the original movie- the date is neither shown nor mentioned. It is not until the second movie that we learn they have gone to October 21, 2015.
