<P> Bill Murray's famous "Cinderella story" scene was improvised based on two lines of stage direction . Ramis gave him direction to act as a child announcing his own imaginary golf moment, with Murray then improvising . The flowers were his idea . Murray was with the production only six days, and all of his lines were unscripted . Murray was working on Saturday Night Live at the time, and was not intended to have a large role in the movie . However, he was repeatedly recalled from New York to film additional scenes as production continued . </P> <P> In interviews, Cindy Morgan stated that the scene she shared with Chevy Chase, in which he pours massage oil on her, was completely improvised, and her reaction to Chase dousing her back with the massage oil, where she exclaimed "You're crazy!", was genuine . The scene where her character had to dive into the pool was executed by a professional diver, but up to that point in the scene, she had to be led to the diving board by the crew and carefully directed up the ladder since she could not wear her contact lenses near the pool and was legally blind without them . </P> <P> An overall deal was made with John Dykstra's effects company for all the necessary visual effects (including lightning, stormy sky effects, flying golf balls, disappearing greens' flags, etc .), so shooting the gopher puppet became part of the intensely negotiated effects package . Dykstra's technicians added extra hydraulic animation to the puppet, including ear movement, and built the tunnels through which he moved . </P> <P> In later years, the production became infamous for the amount of drug usage which occurred on - set, with supporting actor Peter Berkrot describing cocaine as "the fuel that kept the film running". </P>
