In other Back to the Future news, Michael J. Fox, who played Marty McFly in the films, recently spoke out about a health scare from two years ago which was “the darkest moment” in his life.

The actor said he had a noncancerous tumour growing on his spine in 2018, and subsequently had to re-learn to walk across four months.

Fox said that after a successful operation, he fell and badly broke his arm, saying it was his “darkest moment”.

“I just snapped,” he said. “I was leaning against the wall in my kitchen, waiting for the ambulance to come, and I felt like, ‘This is as low as it gets for me.’ It was when I questioned everything. Like, ‘I can’t put a shiny face on this. There’s no bright side to this, no upside. This is just all regret and pain.’ ”
