Continuity mistake: In most shots in the hotel room the houses you can see through the windows are quite far away, like across a wide street. Only in one shot, when Estella stands nude in front of the window, there is suddenly a window only a few meters away, through which one can see an Indian woman with her daughter, surprisingly unaware of the naked Estella.

Factual error: Hawke rides the subway twice during the film. Both times Hawke takes the "G" train. Unfortunately the G doesn't go through Manhattan where he is, it only goes through Brooklyn and Queens.
Continuity mistake: When the drunken Finn is shouting in front of Mrs. Dinsmoor's NY house he is holding a full liquor bottle in the left hand, then he empties it out, holding in his right hand, and finally he throws away a miraculously refilled bottle with his left hand again. (01:18:40)
Plot hole: Before Lustig dies he gives back Finn's scrapbook that got lost during their first encounter. In that scene there is no evidence that Lustig gets hold of the book, and the only explanation would be that Lustig picked up the stranded scrapbook later. This looks quite far-fetched to me, especially since Lustig was hiding in the dunes, and the scrapbook looked way to good to have spent a long time in the water. (01:35:20)
