Continuity mistake: In the final airport chase, when Pacino and De Niro are at the end of the runway, an airplane lands. It is first filmed nose-on, then the shot switches immediately to a from-behind shot after the plane has passed overhead. The plane in the nose-on shot is a Boeing 747, evidenced by the "bulb" above the cockpit area. The plane in the from-behind shot is definitely NOT a 747 - no bulb.
Continuity mistake: The ambulance that de Niro steals at the start of the film has a red stripe on the sides, but for the remainder of the film there is also a silver 'L'-shaped graphic as well.
Continuity mistake: After the first wave of police cars does the "demolition derby" across the spike strip, they show some cops running out to stop the next group of cars. When they do that, the spike strip is not in the street. Then the scene shifts to a close up of the cop cars skidding to a stop directly in front of the spike strip, which has now re-appeared.
Continuity mistake: When they torch the ambulance, you can see a dealership emblem that says "LEADER" right above the Chevrolet emblem on the back door of the ambulance. It is visible right after Chris puts the bomb in. In all other shots with the ambulance, this emblem isn't there. Obviously the "LEADER" ambulance is a "fake" that they used just to burn and destroy.
Continuity mistake: In the shoot-out after the bank heist, Vincent's rifle starts out as an AR-15 style with a carry-handle, but by the time he catches up to Mike, it switches types and has no carry-handle.
Continuity mistake: When the crew's black van is in front of IGM, Trejo turns the parking lights off and there's a shot of Neil coming out the door to hide in the corner. Then they switch to the police monitor where Vincent is watching Neil, and it shows the van's lights are still on.
Continuity mistake: The armored car robbery takes place in the early morning. Waingrow pulling on his clothes, the light in the sky all say early day. By the time Pacino arrives to survey the scene it's pitch black and all the bodies are still on the ground.
Continuity mistake: In the armoured car robbery, when the explosive charge is fired, the windshields of the row of nearby cars all explode outward toward the blast instead of inward away from the blast.
Continuity mistake: In the parking lot, when Waingro escapes being executed, Neil and his crew spread out and look for him. It is nighttime and the sky is clear. Yet when Neil looks out to the distance, it is raining in the last shot.
Continuity mistake: During the scene in Edie's house in which Neil first asks Edie to go away with him 'somewhere', when the camera shot faces Neil he is shown wearing only his white shirt. When the shot changes to the camera facing Edie over Neil's shoulder, we see the dark border of Neil's suit jacket in the lower corner of the screen. This continues throughout the scene, as the shots repeat back and forth with Neil in white shirt only as he faces the camera and wearing his jacket as he has his back to the camera.
Continuity mistake: Vincent's hair (bangs) is at least 3 different styles in the coffee shop scene.
Continuity mistake: In the bank robbing scene, they enter on the street level and since no elevators or stairs are used by them the bank must be on that same level. However, looking out of the windows during the scene it appears they are on an upper floor in the building.
Answer: When Pacino is comforting his wife at the hospital, she says "She chose you. She picked your place." Guess the implication is he had been staying there for a long time and both Justine and Lauren knew where that was. Best explanation I have been able to find.
