This is heavy.
Marty, Doc, Lorraine and Biff reunited during an appearance at Fan Expo Portland.
Lea Thompson, who played Lorraine in the Back to the Future franchise, posted a selfie of her and her BTTF co-stars Michael J. Fox, Christopher Lloyd, and Tom Wilson.
In a video, Thompson hugs Wilson, who played Biff, the neighbourhood bully who was always harassing Lorraine.
For the occasion, Wilson calls her a 'Butthead' and then knocks on her head, asking if "anybody's home," a classic throwback to the films.
Michael J Fox, who played the lead role of Marty McFly, posted a message to Instagram saying, "I love being at these FanExpo events and seeing some of my favourite people like Lea, Tom, Chris and all you #bttf heads. Heavy."
