The New York Comic Convention was the site of one of the most emotional moments of the weekend as Michael J. Foxand Christopher Lloyd, the two stars of 'Back to the Future', were reunited 37 years later.

Marty McFly and Doc Brown are tearing up the space-time continuum again - and it's just as emotional as ever ... especially all these years later.

They starred in an emotional moment when the whole audience gave them a standing ovation.

Together they talked about their friendship, their careers and what it was like filming 'Back to the Future'.

The pair also talked about the illness that Fox has suffered from for more than three decades, when he was diagnosed with Parkinson's disease at the age of 29.

They explained the status of the Michael J. Fox Foundation, the world's largest Parkinson's disease foundation.

"Parkinson's has brought people who are still coming in, but it's a gift, and I wouldn't trade it for anything," Michael explained.

"People like Chris have meant so much to me, and so many of you have too.

"It's not about what I have, it's about what you've given me: a voice to do that and help people."
