It seems that Steven Spielberg is reaching a point in his life where he is looking back at his work and thinking about the things he could have done differently.

It might seem strange for such a legendary director to have regrets about where he went wrong, considering his enormous success across the decades - but the 76-year-old had previously spoken about what he wished he'd done differently on one of his biggest successes, 'Jaws'.

Now, Spielberg has said that there is one thing that he wishes he had done differently in 1982's 'E.T.'

There is a scene in the original theatrical cut of the film where Elliot and his friends are cycling away from police with E.T. in the basket, and the police in pursuit are holding guns.

For the 20th anniversary re-release, Spielberg edited out the guns and instead had the police holding walkie-talkies - but now, he says, it was a mistake to do so.

"I never should have done that," he told the audience at an event in New York. "E.T. is a product of its era. No film should be revised based on the lenses we now are, either voluntarily, or being forced to peer through."

He added: "E.T. was a film that I was sensitive to the fact that the federal agents were approaching kids with firearms exposed and I thought I would change the guns into walkie talkies. Years went by and I changed my own views."

He continued: "I should have never messed with the archives of my own work, and I don't recommend anyone do that. All our movies are a kind of a signpost of where we were when we made them, what the world was like and what the world was receiving when we got those stories out there. So I really regret having that out there."

The topic of censorship arose after Spielberg was asked his opinion on the re-edited versions of Roald Dahl books that have caused huge controversy in recent months.

"For me, it is sacrosanct," he said. "It's our history, it's our cultural heritage. I do not believe in censorship in that way."
