Continuity ... in an animated movie!
Just watching again, for the umpteenth time, and was disappointed to notice this error, early on:
In the fortune teller sequence, Robin removes Prince John's ring, complete, from his left hand, whilst Little John just takes the three stones from his left-hand rings, leaving the three rings and settings behind. However, inside the carriage, when Robin slaps Prince John's right hand, the ring and setting are back again ... minus the stone.
I realise this may be a little picky, but I was just so surprised at seeing this in an animated movie.
There is real life ... and then there are movies!
