Continuity mistake: In the scene where Sean Connery is in prison & Matthew Broderick is visiting - the camera alternates between looking into the cell (at Sean) and looking out (at Matthew). Watch the hands that are holding on to the cell bars - they move each time you get a new shot.
Continuity mistake: During the bar scene where Connery & Brodrick are at a table, Dustin Hoffman comes in and picks up the makings of a sandwich and places them on the table. In the beginning of the shot the salt shaker is near the far right edge of the table, in subsequent shots it has moved to in front of the napkin holder. Also the level & position of the bread slices on the plate changes depending on the shot.
