Revealing mistake: After Axel gets off the phone with Jan, when the trio are driving to the racetrack, in one shot Axel has his arm out the passenger side window as he's holding the red police beacon on the car's roof. Note the stunt double's gold watch instead of Axel's black watch. (01:19:45)Super Grover
Revealing mistake: At the end of the movie, the trio arrive at the oil fields, crouch behind the rear of a car and Axel picks up some red dirt, explaining that it's the same as what was on Bogomil's shoes, and the horse. It is obvious that the crew just spread a small area of red dirt around for the shot. The majority of the area is regular brown dirt.
