Japanese production of The Phantom of the Opera, with a record number of difficulties in one scene! The flubs are, in order of appearance:
1) The boat stops in the middle of the lake, forcing the Phantom and Christine to “walk on water”. Moments later, the boat starts moving again without them (you can see its shape and light if you look closely).
2) The lake candles are still sinking when the Phantom and Christine come back; the gate and lair candles are still moving in.
3) Most amusing - the wedding doll gets caught on the Phantom’s throne when he throws it. It’s funny watching him trying to get it unstuck while trying to maintain character.
