Revealing mistake: When Tango and Cash are getting attacked down the laundry chute, they are tied up above a water tank with a guy holding an electric wire. Their hands are tied to dry cloth which is then tied to the cable. Cloth has no conductivity so there is no complete circuit when their feet are lowered into the water so they wouldn't be getting shocked. The reason they wouldn't be getting shocked is actually explained later in the movie just before they slide down the electric wire.terry s
Factual error: When Stallone shoots the tanker to show that it's being used to transport cocaine, he's apparently stumbled onto the only drug dealers who don't ship cocaine in bricks. There is no way that the coke would flow out of the bullethole like that.
Continuity mistake: Tango and Cash play good cop, bad cop with the bad guy on the roof of the building by taping a grenade to his mouth and intimidate him by threatening to pull the pin. They get the information that they need out of him. Cash says "We scared him so bad, he is standing in a puddle and it's not raining". They then take the grenade, pull the pin and stuff it down his trousers. The next shot is the grenade coming out his trouser leg onto the ground where there is no puddle to be found.
Continuity mistake: When Tango busts through the screen door of his house the screen door breaks apart, but then Cash walks up to him and it's together, lying on top of him.
Continuity mistake: Cash spins out the truck of the bad guy and it stops all forward momentum, but in the next shot it is racing at full speed. The truck then takes out many overhead fluorescent lights. Why has no other vehicle ever hit those lights? Then the truck partially knocks down 7 lights in a row, leaving them hanging vertically. They were damaged enough to knock them off the ceiling - but they are all undamaged enough to still be operating: keep in mind that these are fragile fluorescent lights. But no damage is done to the floodlights on the roof of the truck. (00:08:00)Bill McIntyre
