Factual error: In the scene where Cinderella is in her new room at the Prince's castle, the roses prominently displayed in the foreground are brightly coloured Hybrid Tea roses (the pointy ones) which were not bred until the early 20th Century. In the 1700s (panniered skirts and powdered hair) the roses would have been of looser formation, with softer colours, e.g pink or cream cabbage roses. (These roses also appear in later scenes.)

Question: For 40 years I have wondered why there were two sets of slippers. In the scene after the ball and Edward is holding the lost slipper, the king remarks how small it is, he could have tried them, and they would have fitted. Later in the glass case we see the real small slipper.
