Visible crew/equipment: When the first deal goes wrong and the man with the chainsaw jumps out the window you can clearly see him land on a grey crash mat because it lifts up at the corners.
Continuity mistake: When Tony shoots Manny after he finds out that he has been with Gina, she runs to hold his bloody body, in turn getting blood on her robe. A few scenes later, when Gina comes into Tony's office, wearing the same robe, it is perfectly clean and there is no sign of any blood.
Continuity mistake: Tony and Omar Suarez go down to Bolivia to meet with Mr. Sosa. After Omar has an accident from the chopper,the binoculars are put down on the table on end. Next shot, they lay flat. Next shot, on end again. And so on through out the scene.
Continuity mistake: When Tony is in the Babylon Club watching the performer dressed in a clown suit, the assassins shoot everyone, including the clown. When the clown is first shot, his hat falls to the ground (but the camera cuts away). After a few seconds later, we see the clown again falling, but his hat is back on top of his head.
Visible crew/equipment: Just before Tony gets shot at in the Babylon Club, there is a close up of his face. In the mirror behind him, you can see director Brian De Palma's head.
Continuity mistake: In the scene at the beach/pool where Manny approaches the blonde in the blue bikini, if you watch the area of the pool behind where the blonde is seated on a lounge chair, you will see several people in the pool. Immediately after Manny sticks his tongue out at her and the camera pans back to her as she slaps him, if you look at the same area of the pool, there is absolutely no one there anymore. This was only a matter of seconds after seeing everyone there.
Other mistake: In the scene that begins with "Three Months Later" where Tony and Manny are sitting at the table near the beach watching the girls in bikinis walk by, Manny is attempting to explain to Tony how to pick up women by explaining what "women in this country know and understand". After Manny sticks his tongue out to demonstrate and Tony asks Manny "what the f*ck was that, Mayne?", if you watch Al Pacino's lips as Steven Bauer is talking, you can see Al's lips moving in unison to whatever Steven is saying.
Continuity mistake: In the final scene where Tony is killed, he is shot, then falls through a banister. When he first falls through the banister both halves are pushed outwards. The next shot is from below looking upwards and shows one half of the banister coming outwards and the other going inwards. Then it goes back to the shot from above and both halves are back outwards.
Continuity mistake: In the scene where Tony is watching the blimp go by with the words "The world is yours", if you look at his reflection in the glass he has a cigarette in his mouth. He reaches up to remove it and as the camera changes he is putting it up to his mouth.
Continuity mistake: In the motel chainsaw scene, before the Colombians pull out their guns, there are several food containers, a bag of cookies and a soda can lined up neatly on a table, seen in multiple shots. After the skirmish, Hector pulls the chainsaw out of its box and Tony is leaning against the table with the items now all scattered in different positions. A few minutes later, Manny shoots his way in. You can see the table in multiple shots and the items are back in their original positions.
Continuity mistake: As Tony chases Hector out of the hotel, a white handbag can be seen behind them on the pavement. Afterwards, once Tony shoots Hector, the bag is gone.
Continuity mistake: When Tony leaves the bathroom in the motel scene, the bathroom light is on and it is bright. When he leans over Manny, the bathroom is now dark.
Other mistake: When Tony pulls his arms down from the shower curtain, there are no chains on either of his arms, and at no time do you see them fall in front of him.
