You should watch The Middleman. In the episode "the clotharian contamination protocol."...
- "the nakatomi protocol" in a further driving home of the theme, the keypad chimes with beethoven's ode to joy, the central musical conceit of "die hard".
- "come out to the coast, we'll have a few laughs" - homage by quote (and lucky lighter use) to john mcclaine in "die hard"
- "great, hans grubered with our own robot" - homage to the villain from "die hard,"
- "great, it's "die hard" in a building"
- "now i have a machine gun - ho-ho-ho"
- "yippi-kay-yay [BLEEP!]"
- "now i know what a tv dinner feels like"
- "welcome to the party, ida" - paraphrase of a quote from "die hard"
- "today john wayne doesn't get to ride off into the sunset with grace kelly" - yet another quote from "die hard"
- the "ode to joy" is reprised again briefly when the pneumatic tube chamber opens, echoing the opening of the nakatomi corporation vault in...wait for it..."die hard!"
- "die hard inside an android" - is a screenwriter's joke referring to the glut of films that followed "die hard," all of which were pitched as "die hard in a -"...like "under siege" (die hard in a battleship) or "air force one" (die hard in air force one) or "toy soldiers" (die hard in a military school) or "executive decision" (die hard in a passenger plane) or "sudden death" (die hard in an arena) or "speed" (die hard in a bus) or "speed 2" (die hard in a cruise ship)
Also an episode of Chuck references Nakotomi Plaza as a real place.
Plus there's
this which points up over 200 references in other films and TV shows to Die Hard.
(And, yes, if you look up Back to the Future you'll find an equally long list of references. I'm afraid this one ends in a draw.)
