Miller Outdoor Theater is showing the Back to the Future Trilogy this week! Tonight was the first night and the next two in the series are Wednesday and Thursday this week! Of course...it's FREE! DISH'S favorite price! =)
SO! The answer to the trivia question....
The only "official" (i.e. from the pen of the creators, Bob Gale and Bob Zemeckis) explanation I've ever read regarding this came in the fourth draft of the Back to the Future screenplay. The details were vauge, at best, and it amounted to only a line Marty uttered to his girlfriend: "A couple of years ago, [Doc] showed up at my house and hired me to sweep out this garage of his. He pays me 50 bucks a week, gives me free beer...and gives me total access to his record collection--he's got this great old record collection."
Strangely enough, though, most fan fic I've read has put Marty and Doc's first meeting to when Marty was a kid. That was also the rumor circulating a few years ago when, supposidly, a BTTF prequel was in the works called "Back to the Beginning." I never really thought about Marty and Doc's first meeting prior to reading this line, so I don't know and cannot tell if the friendship is implied to have begun earlier than Marty being about 14 or 15. Certainly Doc and Marty are good friends, but as we cannot "hang out" with them prior to Doc's DeLorean time machine creation, one wonders if the time machine events helped deepen that friendship even more.
For more details on the "Back to the Beginning" rumor, visit the Back to the Future Part IV page on "Back to the Future....The Web Page and scroll down to September 24, 1997.
AND there you have it, DISHIES! See you at the Miller!
