20 Things You Somehow Missed In Back To The Future Part 2
11. Christopher Lloyd Couldn't See Through The Metal Sunglasses
The film of course kicks off with a frantic Doc showing up on Marty's front yard in the DeLorean, while memorably wearing a pair of silver metallic shades not unlike those worn by Bret "The Hitman" Hart throughout his wrestling career.
Hilariously, though, the sunglasses didn't actually function as glasses you could see through, and so Christopher Lloyd had to basically play the scene as blind until Doc removed the glasses.
Watching the scene with this in mind is totally hilarious: Lloyd clearly uses the DeLorean to steady himself while running towards Michael J. Fox, and his eyeline doesn't even nearly match up with Fox's face.
Thankfully Lloyd only had to keep the charade up for about 15 seconds before removing the shades, but even so, his blindness is impressively missed by most fans.
