So now you've got that going for you, which is nice.
Inspired by Brian Doyle-Murray's experiences as a caddy in his youth, this wild, anarchic film is about more than just golf. Without a doubt, it's my favorite comedy, and might even be one of the greatest movies of all time. There is not a single scene without comedic chaos.
Director Harold Ramis is barely able to contain the insanity. There is honestly so much in Caddyshack, there's enough for ten movies, hardly surprising since the first draft of the screenplay was 199 pages long while the first cut of the film run for 310 minutes. I imagine that there's enough cut out to make whole new Caddyshack movies. There are about five different plots developing at once throughout the movie, the funniest of which is Carl Spackler's (having been licensed to kill by the 'Government of the United Nations') attempts to assassinate a rogue gopher tearing up the golf course.
Each and every actor battles with each other, and it's hard to nail down exactly who runs away with the movie, but if I absolutely HAD to choose, I'd say that Rodney Dangerfield's sleazy, slobbish, overly-friendly, and gratuitously tipping character is the most wonderful thing about it. He is the perfect foil for Judge Smails (an utterly perfectly-cast Ted Knight), a pompous, bad-tempered, self-important hypocrite who wants to reserve the pretentious Bushwood Country Club for snobs and gentlemen (despite being far from a gentleman himself).
If you like comedy quotes, Caddyshack is a goldmine. There are hundreds, literally hundreds, of lines worthy of repeating in real life. You could literally get by, from cradle to the grave, just quoting Caddyshack, and it would bring you nothing but pure happiness and good fortune.
The Blu Ray features a 1080p 1.78:1 picture that is a HUUUUGE step-up from the DVD, with DTS HD-MA sound, and loads of extras.
