Christian Marclay's "Telephones" (1995), a 7 1/2-minute compilation of brief Hollywood film clips that creates a narrative of its own. These linked-together snippets of scenes involve innumerable well-known actors such as Cary Grant, Tippi Hedren, Ray Milland, Humphrey Bogart and Meg Ryan, who dial, pick up the receiver, converse, react, say good-bye and hang up. In doing so, they express a multitude of emotions--surprise, desire, anger, disbelief, excitement, boredom--ultimately leaving the impression that they are all part of one big conversation. The piece moves easily back and forth in time, as well as between color and black-and-white, aided by Marclay's whimsical notions of continuity.
If you know a similar movie, please feel free to share it here. :)
One of my favourite compilation is made to Carl Sagan speech about Pale Blue Dot. Movie compilation is starting from 2:07, but i recommended to watch full movie :)
The couch gag / opening scene from this years Simpsons halloween episode, directed by Guillermo del Toro, tributes to a mix of his own films and many horror classics (Frankenstein, The Birds, Phantom of the Opera). Even our own stolen Hypnotoad!
