It's now been 36 years since the first Back to the Future movie.
But stars Michael J. Fox and Christopher Lloyd are still great friends, and they had a rare reunion at Awesome Con in Washington over the weekend. Here are the pictures of their get-together.

On Instagram, Fox, 60, posted a nice shot of himself and Lloyd, 82, relaxing in a golf cart. "Back to back," Fox captioned the photo, while Lloyd added in the comments, "Best of times."
Lloyd also shared a picture of his own on his Instagram, showing the retro movie duo having a friendly chat. "Caption this..." he wrote to his fans, who had some fun responses to the post.
Of course, Fox and Lloyd played their parts as "Marty McFly" and "Doc Brown" in the Back to the Future films of the 1980s.
They starred together in the original film 36 years ago, and the trilogy's final chapter was released in 1990.
Though now in his 80s, Lloyd is still acting today. He has several new projects due out in the near future, including a role in George Clooney's film The Tender Bar.
Last year, Fox released a memoir that announced he recently retired from acting due to the effects of his Parkinson's diagnosis.
