Revealing mistake: During the scene in which Krendler shows the fake Lecter postcard, look closely and you can read the line: "Sounds like him to me" although this line is part of Krendler's speech, and not part of the message itself. Forgetting your lines, Mr. Liotta? (01:21:55)
Revealing mistake: At the end of the telephone conversation between Krendler and Verger we see Krendler with his mobile phone, and through Krendler's phone we hear Verger hanging up. The sound we hear is unequivocally that of a receiver being hung up on a desktop telephone, but in all of the shots portraying Verger in this sequence we see him using a mobile phone. With mobile phones a conversation is ended simply by pressing a button-there is nothing to hang up. (01:21:20)
Revealing mistake: When Pazzi is killed, there's a shot of his cell phone and phone battery slamming into the ground followed by a splatter of his innards. However, there is a (rather obvious and poorly timed) jump-cut in the middle of the shot, right before his innards splatter down from above. His cell phone is still moving about a bit, when suddenly it goes perfect still in an unnatural way. It also moves ever-so-slightly to the left when the cut happens. It's supposed to appear to be one continuous shot, but it's clear they dropped the cell-phone, waited for it to settle, then dropped the innards and tried to edit it so the shot moved faster.
