Chris Farley as Shrek? It Almost Happened [Video]
It's hard to imagine the role of Shrek being voiced by anyone other than Mike Myers, but the part originally belonged to Chris Farley who actually recorded most of the dialogue before his death in 1997.
This is almost surreal, but I found this clip of Farley voicing Shrek, with Eddie Murphy filling in the donkey, along with just working storyboards for video. Pretty interesting.
