commentary the roles that  Harrison Ford (I) (qv) and Josh Hartnett (qv) play in the movie  are almost reversed in real life. Gavilan (Ford) is a good shoot and  almost a stunt driver. Calden is a lousy shoot and driver. In  reality Ford does not like guns and is a very poor shoot at best  while Hartnett is a very good marksmen, having been through actor  basic training for two other movies (_Pearl Harbor (2001)_ (qv),  _Black Hawk Down (2001)_ (qv)) twice. Hartnett on the other hand  does not like to drive while Ford is, according to  Ron Shelton (qv), "...a maniac behind the steering wheel".
