Phixius

Corrected entry: After the cafe scene at the beginning of the movie, the camera pans across the 'dead' body of the gunman, who is still clutching the said weapon after shooting himself in the head. However, this cannot be possible, as the force of the shot would have blasted the gun out of his hand and across the floor.

Correction: Either he didn't die right away (it's possible, Google "Phineas Gage") or his muscles seized up sufficiently to allow him to maintain a postmortem grip on the gun.
