Miscellaneous: When the robbers and some people are in the bank elevator, one girl wears a light-blue dress. Some minutes later, after the robbery, she talks to the police wearing a light-green dress.
Factual errors: The haul from the first bank robbery totals $2,660,527.62, as explained by the police. It is broken down in to 16,240 $20 bills, 19,871 $10 bills, 34,465 $5 bills, and 129,000 $1 bills. Added up, that only totals $824,835.00, as later detailed by a secretary. That makes the whole greater than the sum of its parts.
Continuity: During the infamous chess scene an overview of the board is shown as Vicki Anderson moves her bishop forward that shows that Crown has already castled, but it is not until later in the scene that he actually performs the move.
Continuity: During the first getaway scene in the picture, the driver is scene driving westbound on the Massachusetts Turnpike a mile or so into the highway from downtown Boston. He's then seen *entering* the Pike from I-93 which would have happened prior to already being on that road. Subsequently, he's seen further down the Mass. Pike, once again somehow traveling westbound on it as he was before.
