When Michael J. Fox was filming Peter Jackson's 1996 cult horror/comedy The Frighteners, he kinda forgot what movie he was in...more than once! Instead of yelling for the Judge, he yells for...you guessed it, "DOC!!" Hahaha!! Check out the hilarious blooper! It's only 43 seconds long.

I've mentioned time and time again about my love for the Back to the Future trilogy, so to me, this was internet GOLD! Also, if you haven't seen The Frighteners, do yourself a favor and pick it up. The video is slightly NSFW due to some adult language.
