Back to the Future

'Back to the Future' is arguably Robert Zemeckis' magnum opus, and the flick had no trouble impressing at the box office.

The 1985 film – which starred Michael J. Fox, Christopher Lloyd, Lea Thompson and Crispin Glover – was made on a budget of $19 million, and finished its theatrical run with over $381 million.

Despite the success of the movie and its two sequels, Zemeckis is adamant there will be no more instalments in the 'Back to the Future' franchise.

He said: "There will never, ever be, in the most absolutely way, a 'Back to the Future 4'.

"I'm sure Universal would love it if we were to say to them, 'Hey, let's do another one', but we don't think we could ever make a fourth one that would live up to how great the first three are, so we're going to leave well enough alone."
