Robert Zemeckis will block any attempt to make another 'Back to the Future' movie.

The 63-year-old director - who created and directed the original sci-fi movies, starring Michael J. Fox - has admitted that while another film would be commercially successful, he hopes it never comes to fruition.

Asked if he'd like to make another 'Back to the Future' film, Robert said: ''Oh, God no.

''That can't happen until both [co-writer Bob Gale] and I are dead. And then I'm sure they'll do it, unless there's a way our estates can stop it.''

What's more, the director said it'd be difficult to do a remake as the original story and the movie's stars are so iconic.

He told the Daily Telegraph newspaper: ''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?''

The original 'Back to the Future' movie was released in July 1985 and has made close to a billion dollars worldwide.
