The first I remember was Jackie Chan’s Rumble in the Bronx. But surely that was not a hollywood movie was it?
I seem to recall that ‘Smokey and the Bandit 2’ had them. That hideous thing with the elephant and Dom Deluise.
I first recall them in “Cannonball Run”. Not making a claim that that was first, though.
My guess is Being There (1979).
I was going to say **Being There ** as well. As I recall, the director Hal Ashby and Peter Sellars were both vocal in their disgust that the studio had done this.
Being There is the first I remember as well, I saw it on HBO. And I remember laughing my butt off, even at age 11 or 12. I watched the movie again on video in the late 80s and the out takes were gone. 
And who cares if the director and star didn’t like it anyway?
Considering that they’re both dead, probably nobody. But how do you think an author would feel if his/her novel was published and the publisher included extracts from the first draft at the end?
Being There wasn’t the first by a long shot. Hooper (1978) beats it, and so does Smokey And The Bandit (1977). In fact, has there ever been a Hal Needham movie that didn’t have this feature?
Plan 9 From Outer Space? No wait, those were things that should have been outtakes, but they stitched a film together out of them instead…
waits, I wouldn’t worry much about the author either.
