Last Vegas (2013)

Factual error: In the scene where they are heading towards the Aria hotel to check for hotel rooms, they walk past the volcano at the Mirage. They are walking in the opposite direction (away from) the Aria hotel.

Continuity mistake: In the scene where Sam takes the girl to the hotel room villa, you can see his tie/scarf goes from being on both shoulders, to one shoulder, then back to both.

Revealing mistake: Early on when the guys are going to New York to pick up Robert De Niro there's an aerial shot of New York/Manhattan. In it you'll see the helicopter's shadow on the Brooklyn Bridge, and it is traveling in reverse. Also the flag on the top of the bridge is not flying properly.

Sam: We have a problem. The rooms aren't gonna be ready for another year and a half. They're still remodeling. Archibald, did this topic come up when you made the reservation?
Archie: No, because you insisted on making the reservations.
Sam: I insisted, but then you insisted. And it is the second insister.
Archie: Sam.
Sam: That supersedes the.
Archie: Sam. I offered, you insisted.

Billy: Welcome to Las Vegas.
Paddy: Relax, Gershon, it's not like you invented it.

Billy: Why every time the phone rings you think somebody is dying.
Sam: I live in Florida now, usually when the phone rings somebody is dying.
