Dude, I don't get your response. What's this YouTube link got to do with my thread? Is it that you like my idea and think it should be used for the project? Or do you not like my idea and prefer the idea that the Paradox Film Project people have come up with? Or have you just put the link in randomly because you want as many people to see it as possible?

The codes are different for every DVD/Blu-ray purchased. It is illegal to use someone else's code to download the digital copies.

 Here's my idea for a Back to the Future 4:

• 28th October 1985- a 35 year old scientist, with a personality very similar to Doc Brown's (we will call him Doc 2), discovers the wreck at the train tracks and notices the time curcuits. He thinks this might have something to do with Doc Brown and when people start worrying about where Doc is, he visits Doc's lab and finds a journal showing how he created the time machine. So Doc 2 uses the journal to repair the time circuits and the flux capacitor and attaches them to his own DeLorean (the exact same model as Doc Brown's). However, the journal has no information on Mr Fusion, so he assumes that it came from 2015 (the journal explains Doc's time travel plans). Doc 2 decides to wait until Mr Fusion becomes available, since Doc's remaining plutonium has been confiscated by police and he doesn't want to risk ripping it off.
• Something bad happens to Marty and Jennifer somewhere between 1985-1990 that destroys their lives forever.
• In 2013, Marty Jr. becomes friends with Doc 2 just like Marty Sr. did with Doc Brown. Doc 2 is unaware that Marty Sr. was friends with Doc Brown and knew about the original time machine.
• The film starts just like Part 1 except in 2015. Doc 2 asks Marty Jr. to meet him at the Courthouse Mall parking lot. The DeLorean has been hover converted and is identical to the DeLorean from Part 2. Marty Jr. gets sent back to 1985 on the same day Doc 2 discovered the wreck. When he arrives, Biff sees the DeLorean flying and is more curious than ever to find out what the hell is going on.
• Marty Jr. encounters his father, who, remembering his visit to 2015, recognises his son. They have a conversation about how each of them knows about time travel, which Biff overhears part of. Biff then begins to put the pieces together: the flying DeLoreans in 1955 and 1985 were the one time machine, the almanac and the guy who gave it to him were from the future (although he does not realise it was his older self yet) and Calvin Klien was, in fact, Marty. So he decides to go back to the night of the dance to stop Marty from getting the almanac back. He may also decide to intercept George to allow young Biff to rape Lorraine and erase Marty from existance so he cannot go back and recreate history.
• During the film, Marty Jr. prevents the incident that destroyed his family's life.
