Michael J. Fox and Christopher Lloyd go back to Back to the Future to rate the movie's 2015 predictions

It's been nearly 30 years since Doc Brown and Marty McFly fast-forwarded to October 21, 2015 in the '80s classic Back to the Future.

To commemorate, Michael J. Fox and Christopher Lloyd - who played Marty and Doc, respectively - reunited to see how well the 1985 movie predicted the future, aka five days from today.

Watch their banter in the clip above.

The ex-co-stars got together to promote Toyota's forthcoming futuristic hydrogen gel car, which is just one of the things that Doc and Marty definitely didn't see coming.
