Trivia: After Marty and Doc arrive in 2015, Marty sees a news alert that the Chicago Cubs have won the World Series. On the real October 21, 2015 - the date at which Doc and Marty arrive in the film - the Cubs were eliminated from the playoffs after getting swept in the NLCS by the New York Mets, but won the World Series a year later.
Trivia: The 2002 DVD release of both this film and of Part III is very misframed, with many elements cropped out of frame or not centered properly. The most obvious example is when Doc demonstrates the adjusting sleeves on Marty's 2015 jacket (the sleeves are cropped out of the frame so that you can't see the effect), but nearly the entire movie is misframed. The disks were later reissued with corrected framing, and all later DVD and Blu-ray editions have correct framing.
