Continuity mistake: When Willy asks the decorator on the phone what's the difference between Italian and English, his Samsung Blade switches hands, switching back when he holds it against his chest. (00:33:05)

Continuity mistake: When Willy rings Crawford's doorbell, notice a white control panel below the CCTV screen. Hopkins then answers the door in a different shot, with the panel missing. The panel was always there during his earlier scene with Nunally, and it is still there for the rest of the scene, missing again only in a later zoom-in on the monitor as Crawford checks on the prosecutor. Probably those were later reshoots. (01:39:25)
Answer: Crowford (Hopkins) shot his wife with the gun that belonged to Nunally (Burke), but switched it with his at a moment of Nunally's distraction. The gun that the police mistakenly collected was not the murder weapon. This was a key plot point. Crowford goes on to gloat about it near the end of the film, saying the one piece of evidence Nunally needed was on his hip the whole time.
