  • Constantine's driver's license on line 5 gives his number as "CONST6610-1-ABFC121-1". This is not a correct UK driving license number, which should consist of the first 5 letters of his surname and then his date of birth jumbled, followed by the first 2 initials of his first name (if only 1 initial the second will be a 9), then computer check digits (in case there is someone else with the same name and date of birth), then a space and the issue number. There are no "-" in the driving license number and the only space is between the driver number and the issue number. In reality, Constantine's license number would likely be "CONST805102J99AB 35".
  • To distract the security at the mine, Constantine uses a nearby backhoe loader, dumping the rocks on its bucket. However, the lever he uses to do so is handbreak, not an attachment control lever.
