Continuity mistake: When Daniel and Julia visit the Past Lives Pavilion, they show everyone coming in to where the booths are in a single line. The PA announcement tells them to take the first available booth on the left, yet they all walk to the end of the row and THEN pick a booth.
Other mistake: When Daniel is at the Italian restaurant with Julia, the waiter says he will bring Daniel 9 pies. When Daniel is carrying them into the hotel after dinner, it is clear is only carrying 8 pies.
Continuity mistake: When Daniel and Diamond are having lunch, Diamond is drinking some red drink and Daniel has water. Both glasses jump all over the table and the liquid levels change as well.
Continuity mistake: At the Italian restaurant, Daniel asks for just a touch of cheese on his broccoli. With the camera on the broccoli, Eduardo pours so much cheese on it that it overflows. Off shot you can see him continue to pour, so you'd assume that it would be absolutely saturated and a big mess, but when they pan back to the table, the broccoli has very little, if any, cheese on it.
Continuity mistake: When Albert Brooks is watching the weather channel in his room, the TV has a scrolling bar which says Temperature 76 degrees, and perfectly clear. However, a couple of scenes later when he is leaving the hotel on his way to see his lawyer, you can clearly see clouds in the background.
Continuity mistake: In the Italian restaurant, the couple sitting behind Julia (over her left shoulder) switches between a young couple (female dressed in a dark suit) and an elderly couple dressed in the white.
