During rehearsals and filming of Count Dooku’s lightsaber battle scenes, a small model of Yoda was used as a reference point for Christopher Lee. The model however was slightly altered to have vampire fangs, to which Lee’s amused response was “I will not comment on that. I didn’t think you would do this to me, George!” The fangs were likely a joke at Lee’s expense for his performance as Count Dracula in Horror of Dracula (1958) and several other Hammer Studios horror films.
