In this era of remakes and reboots, the only way we'll ever see a return to "Back to the Future" is over the director's dead body.

"Oh, God no,” Robert Zemeckis replied when asked by The Telegraph whether he'd ever approve a remake of the beloved 1986 sci-fi comedy.

“That can’t happen until both Bob and I are dead," he continued, referring to co-writer Bob Gale, who shares the rights to the franchise. "And then I’m sure they’ll do it, unless there’s a way our estates can stop it. I mean, to me, that’s outrageous. Especially since it’s a good movie. It’s like saying ‘Let’s remake "Citizen Kane." Who are we going to get to play Kane?’ What folly, what insanity is that? Why would anyone do that?”

Zemeckis explained that his and Gale's 1984 contracts with Universal Pictures and Amblin Entertainment stipulate that they have final say on any "Back to the Future"-related film as long as they live.

The 1984 film earned Gale and Zemeckis an Oscar nomination for Best Original Screenplay, and of course spawned two sequels. The two also wrote a "Back to the Future" musical that's expected to premiere this year in London.
