Continuity mistake: When Mrs. Thrall appears first she is called Annette. In the gallery scene she is called Erica. (01:03:40)
Continuity mistake: When Finn runs to Ping's restaurant to meet Estella he is almost hit by a car. You can see that all other cars, which are scattered along the road, aren't moving. (01:08:20)
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)
Continuity mistake: When Lustig comes to Finn's appartment he reveals his identity by replaying the scene in the water, when they first met. Right next to Finn's head you see a decorative mobile with vigorously swinging birds. In all other shots the mobile is completely motionless and in quite a distance from the spot where this conversation takes place. (01:25:00)
Continuity mistake: Lustig's murderer enters the subway car through the connecting door. After the stabbing he runs back and tries to leave through an exit next to this door. However, in the previous shots Lustig and Finn were standing right at that exit, which means that the stabbing shot was taken at a different spot than where the two protagonists were shown before, i.e. it was taken farther away from the connecting door. (01:33:30)
Continuity mistake: Mrs. Dinsmoor doesn't visibly age over a time span of about 15 years.
