20. Bill Murray and Chevy Chase Didn’t Get Along
Murray and Chase didn’t have the best relationship before Caddyshack. Bill Murray actually replaced Chevy Chase on Saturday Night Live, causing tension on the set of Caddyshack. To help, the producers originally intended that the two would never appear in the same shot, but after some time, the two worked their issues out long enough to film a scene entirely improvised by the actors where Chase’s character wanders into the gardening shack.
