Quoted from J85M:
That will never happen Bob Gale has said multiple times on record, he wont allow BTTF to be remade, think his exact words at one convention where along the lines of "yeah I have been asked if a remake is an option, my response was over my dead f**king body that will happen"
And Robert Zemeckis I believe is in complete agreement with him on the matter, honestly though I don't think it needs remaking it is truly timeless and imo one of if not the best trilogy ever put to film.
As much as I hate remakes, this one I'd be OK with. I'd love to watch a kid from today get stuck in the 80's. I'd feel like my dad did watching the original when it came out.
Besides, the President joke still works.
"Tell me future boy, who's President of the United States in 2018?" "Donald Trump." "Donald Trump? The real estate tycoon?!?!?"
"I suppose Ivana Trump's the first lady!"
