Recycled Disney [VIDEO]
When I was a kid, I always loved the movie "Snow White and the Seven Dwarfs." It came out in 1937 and was Walt Disney's first full length production. Most of the animation these days with all done with computers, but before that everything had to be drawn by hand so at Disney they reused some scenes including the one above from Disney's "Robin Hood" that came out in 1973. According to the Wikipedia page on the movie (which you need to take with a grain of salt):
As the film was allotted a small budget, the artists referenced footage from previous animated features. A dance sequence was traced from sequences originally produced for Snow White and the Seven Dwarfs, The Jungle Book, and The Aristocats.
