Mr Strickland: "No McFly has ever amounted to anything in the history of Hill Valley!"
Marty McFly: "Yeah, well, history is gonna change."
If you were a child of the 80's, chances are that you would have owned one or more of the Back To The Future movies on VHS as a kid (or in my case, a very treasured copy recorded from TV with the ads cleverly edited out). Fast forward to the 21st century, and now the trilogy is available in a box set of Bluray discs. It's striking to note that the original films haven't needed to be tampered with; beyond some deleted scenes and the soundtrack being remastered, there hasn't been a need to update the visual effects or change the pacing of the films with extended cuts.
