Other admirers have included special effects artist Ray Harryhausen, who writes in his autobiography "An Animated Life", “Long before Obie (Willis O'Brien), myself, and Steven Spielberg, he put flesh on creatures that no human had ever seen. […] At the L.A. County Museum I vividly remember a beautiful Knight mural on one of the walls depicting the way the tar pits would have looked in ancient times. This, plus a picture book about Knight’s work my mother gave me, were my first encounters with a man who was to prove an enormous help when the time came for me to make three-dimensional models of these extinct beings”.
