When auditioning for his "M*A*S*H" (1972) role, Christopher essentially ignored the monologue prepared for him and instead ad-libbed a rambling speech in a priestly tone. While the producers were disappointed that he didn't deliver his prepared lines, they liked his performance and manner well enough to offer him the role--on the condition that from then on, he would stay with the script.
