Other mistake: In a scene toward the end of the film, there is a shot showing a calendar with the month March 1998. It shows Friday as being the 13th (reference to Philip Morris' birthday), but Saturday appears as the 15th. Did the actual month of March, 1998 not contain the 14th?
Continuity mistake: In a scene where Philip goes is in prison, it shows "08" as the year on one of the prison monitors. This part of the story takes place in 1998. (01:10:27)
