Animation takes AGES to make, so over the years, some of the smart folks at Disney have recycled some of it.
By tracing new characters over old ones, they copy the movement to make new animation much more quickly! Here are some examples you might recognise...
Snow White and Marion
Marion may not be human, but she's close enough to match Snow White's clapping perfectly
Aristocats and Robin Hood
In the same scene from Robin Hood, there's some Aristocats inspired boogie
Dancing dwarves and dancing merry men
Did the merry men have any dances of their own?
Mowgli's wolves and Wart's wolves
Both Mowgli and the young King Arthur were dog, or wolf, lovers!
Little John and Baloo
Apparently it only takes some green clothes and hair dye for Baloo to pass as Little John!
Princes on horseback
Sleeping Beauty's Prince Phillip and Wart's useless brother Kay ride a very similar horse...
Aristocats and Dalmatians
Cats everywhere get into the same sorts of trouble it seems!
The Prince and the Princess
Aurora and Belle obviously had the same dance tutor!
