Continuity mistake: In the restaurant scene, Jackie and Mickey are having a discussion. The latter drinks martinis and then steals the former's beer. In one shot, Mickey's drinking deeply from the beer glass, and then puts it down, but in the next shot, there are only martini glasses on the restaurant table.
Suggested correction: Starts w/ 2 full beers, M sucks "that beer" down as if there's only 1. Waiter comes back with 3rd martini, M asks if he brought J a beer, but there's still a full glass on table. After waiter leaves there are 2 full beers on table again! Then Mickey's drinking a half glass of beer! Waitress brings another martini, right after that there's half glass of beer and empty martini glass! Then back to full glass of beer and another half glass and 2 martinis, 1 half full. Then back to 1 beer/1 martini, etc.
