Bill Murray’s performance as the unhinged groundskeeper Carl Spackler in Caddyshack (1980) became iconic precisely because of how unstructured, improvisational, and short his time on set actually was.
Murray was originally cast in a minor, near-silent cameo role. Because of his tight Saturday Night Live shooting schedule, he was only available on set at the Rolling Hills Golf Club in Davie, Florida, for six days. Director Harold Ramis and co-writer Douglas Kenney had only a basic frame for the character, allowing Murray complete freedom to build Carl Spackler on the fly.
Virtually none of Murray’s iconic dialogue was written in the script. The speech where Carl imagines himself winning the Masters while taking a grass whip to a bed of chrysanthemums was completely ad-libbed. Ramis simply instructed Murray to act out a kid imagining a sports fantasy, and Murray did the entire scene in two takes. His story about caddying for the Dalai Lama (“Gunga galunga... total spiritual enlightenment on your deathbed”) was improvised on the spot.
Because Murray and Chevy Chase were the film's two biggest SNL stars, executive producer Jon Peters realized midway through shooting that they didn't have a single scene together. Ramis wrote a brief setup where Chase’s character, Ty Webb, accidentally plays a golf ball into Carl’s dilapidated shack at night. Murray and Chase ad-libbed the entire exchange in one evening shoot, creating the famous scene where Carl offers Ty a drink of “a hybrid of bluegrass, Kentucky bluegrass, feathertex and northern California sinsemilla.”
The production of Caddyshack was famously chaotic, fueled by heavy drug use, late-night partying, and erratic weather. Murray was known for staying in character between takes, wandering around the golf course harassing real country club members, driving groundskeeping equipment into water hazards, and playing pranks on the cast and crew.
