This is such fun news! The cast of one of our favorite 80's movies got together for a fan fest over the weekend! Over 37 years later, the cast of “Back To The Future” is back in time. Star Lea Thompson shared a picture on Instagram of the major cast’s reunion at Fan Expo Portland. Thompson’s photo included herself, Christopher Lloyd (Doc Brown), Michael J. Fox (Marty McFly) and Tom Wilson (Biff Tannen). If you want to see more photos and videos you can check out Lea Thompson's instagram (where this photo came from) by clicking here.
