Continuity mistake: When Jack is outside Dunlop Plaza, talking to Nina on the phone, he says, "Nina, it's Jack." But the transcript Tony looks at a few seconds later reads, "Nina, it's me, Jack." (00:17:15 - 00:18:00)
Continuity mistake: Shortly after the clock display reads 01:44, the time is shown again... and it's 01:42. (00:29:20 - 00:30:25)
Continuity mistake: When Richard is shot and on the floor, there is a blood blob above his shirt pocket that keeps disappearing and reappearing. (00:35:10)
