Corrected entry: When the Foot soldiers hold Donatello's head in the fishtank, after Donatello pulls his head out and spits the water at the foot soldier, the Foot soldier clutches his face and groans as if he had just been sprayed with acid. But the foot soldier is wearing a mask, in which case the water couldn't have gotten anywere near his eyes.
Corrected entry: When the two turtles are waiting for the pizza guy to come to their sewer grate, one of them is sucking on a popsicle stick. The actor in the turtle suit can't see what he is doing, though, and subsequently pokes himself in the face with the stick a couple of times before finding the mouth of the costume.
Corrected entry: Because Michelangelo has a pair of nunchaku, BBFC policy at the time of the original release in 1990, was to edit out scenes involving the use of chain sticks because it was feared they could be imitated, so the film was cut for this reason. These cuts were rescinded by the BBFC for its recent re-release in cinemas.
Corrected entry: When April's phone is hanging through the ceiling during the fire, the actual phone is off the hook when it starts ringing.
Corrected entry: When the fire in April's apartment starts, her phone is hanging through the ceiling when it starts ringing - the phone is one cord short. It could be the phone line (which would explain the voice message stopping when the line snapped), but that would mean the phone had no power. If it was the power cord, where is the phone receiving the call from?
Corrected entry: It seems pretty odd that four mutant turtles and a mutant rat could come by a staff, a pair of sashes, a pair and nunchucks, and a pair of katanas. Breaking into a place is unlikely because of Splinter's beliefs and they surely couldn't waltz into a store and purchase without some confrontation.
Corrected entry: When the Turtles are fighting the ninjas in Aprils apartment and the floor caves in. When the shot shows the basement as the floor falls through, you can see a person at the bottom right of the screen throw up their hands in front of their face. Im guessing that this may be the demolition guy that makes the floor fall.
Corrected entry: When the turtles are fighting the Foot in April's flat, it is daylight. However when they have to evacuate because of the fire, it is pitch black.
