Despite having little experience as a no-name actor, Murray’s talent shone in Caddyshack. It was his first major film, but Murray is such a great comedian that even this early on, he ended up improvising all of his lines in the movie, including cutting the flower tops off with a grass whip. His lines have been called some of the greatest movie quotes of all time.
