Dr. Emmett Lathrop "Doc" Brown, Ph.D., is perhaps the greatest scientist the world has ever seen. Aside from managing to popularise an otherwise doomed brand of car, Doc created a time machine just by making it drive at a casual 88mph. This goes some way to explaining the logic behind the German autobahn.
It is not known where Doc is at present. He was last seen riding a steam locomotive into a time unknown with his wife Clara and sons Jules and Verne... as you do. My guess is he went to visit William Wallace - Great Scott!
Christopher Lloyd started his acting career in the theatre before making the switch to the big screen with One Flew Over The Cuckoo's Nest alongside the likes of Jack Nicholson and Danny DeVito. He has consistently played roles under the radar, although undoubtedly his biggest role came in the shape of the eccentric Doc Brown on Back To The Future alongside Michael J. Fox.
Since the hugely successful and critically acclaimed Back To The Future franchise, Lloyd has mostly returned to more minor roles with the notable exception of playing Uncle Fester in The Addams Family (1991).
