This would happen AFTER Old Biff returned with the DeLorean.

But if that's true, how did Old Biff manage to get back to the same future that he left? Shouldn't he have come back to a different future?Īs should be clear from the answer to the previous question, we believe Old Biff DID indeed return to a different future - a '2015-A,' which would have transformed around Marty, Doc, Jennifer and Einstein (just as Doc explains how 1985-A would change into 1985 and instantly transform around Jennifer and Einstein). When Doc and Marty are in 1985-A, Doc says they can't return to the future to stop Biff from stealing the DeLorean, because it would be the wrong future. However, the vast majority of the audience did not understand it, so we decided to cut it out, leaving the answer ambiguous, and subject to various interpretations - besides the above explanation, you can believe that Old Biff had a heart attack from the shock of time travel of from flying the car, or from something that happened to him in 1955. After old Biff clutches his chest and staggers (the same symptoms that Marty exhibited in Back to the Future when he was beginning to be 'erased'), we actually filmed him falling onto the street and vanishing, and we previewed the movie this way. (Probably, Lorraine shot him sometime around 1996!). Our intention regarding old Biff was that upon his return to 2015, he would be erased from existence because he had changed his entire destiny by giving his younger self the Sports Almanac. What happened to old Biff when he staggered out of the DeLorean in 2015? As far as we know, Nike has no current plans to develop such a shoe. It's purely a special effect, and those shoes do not really exist. Where can I get a pair of those self-lacing shoes that Marty had?
