Back to The Future stars Michael J. Fox, Christopher Lloyd, Lea Thompson, and Thomas Wilson reunited over the weekend, 33 years after the 80s classic was released in cinemas.

The foursome appeared at a Fan Expo in Boston — where they discussed the possibility of a fourth instalment in the franchise, which birthed three films from 1985 to 1990.

"Basically, I think America is saying, 'Come on they've wrecked every other franchise with bad sequels, why not this one?' " said Wilson, who played Biff Tannen in the film.

This was special.

The cast members and old friends shared photos from their reunion across social media — and it seems even they couldn't believe they were all together after so long.


"This was special," wrote Lloyd, 79, who played Doc Brown in the films.

"Back in 2018, even Biff made it," wrote Fox, 57, who played Marty McFly.

"Four old friends get back from the future," wrote Thompson, 57, who played McFly's mother Lorraine.

Speaking to in 2015, Christopher Lloyd revealed he almost knocked back the offer to appear in the film.

"At first I was going to turn it down," he said. "I was planning to go back to New York to pursue a theatre career — that's where I started out.

"I really had to think about the film. There was some hesitation."

The franchise was a massive success and one of the biggest pop culture phenomena of the 1980s, the three films pulling in almost a billion dollars at the box office.
