Other mistake: When Nardo is piercing John's ear, it's obviously just him and the Sharks, but then in the shot from above, you can see all the Jets running to the rescue. Also, Ice is already there, throwing a Shark off of John.
Other mistake: During "Cool," Baby John spins around and when he stops with his arms spread out, his right foot stumbles a little. (01:58:15)
