For those who love Shrek and Mike Myers as the voice of Shrek, the original plan was completely different! Chris Farley was cast as Shrek originally and had almost all the lines recorded for the movie just before he died. Even the personality of Shrek was different. The original concept was to make Shrek a little bit more like Chris. like a humble, bumbling innocent guy. The audio leaked on Reddit and is spreading like wild fire on the web now.
