Harry Potter and the Order of the Phoenix
If you were happily under the impression that the world of Harry Potter was a real place, I’m sorry to burst your bubble. The truth is that green screens, and hands, are the real deal. But we should be happy that this works because it means the wizarding world can come to life on our screens!

In Harry Potter and the Sorcerer’s Stone from 2001, the floating candles in the Great Hall were done using candle-shaped holders with oil and burning wicks that were suspended from wires that moved up and down on a special effects rig. It made it look like they were floating. But one of the wires snapped, due to the heat, causing the candle to fall to the floor. While no one was injured, the decision was made to re-create the candles using CGI for the next movies, as using real candles was a safety hazard.
