One of the opening shots shows Saunders driving the truck and Littlejohn dozing in the passenger seat. The view changes to briefly show the truck from the outside. It changes back to show the two men inside, and now Littlejohn's arm is on the back of Saunders' seat. It wasn't there before.
During the prologue when Littlejohn and the driver are strafed by the aircraft, he identifies it as a Messerschmitt. The plane has squared off wing tips and a bulging belly and is clearly an American P-51 "Mustang".
When the 3 German soldiers come to the boat the get Littlejohn, 2 of them are killed by a mine under a wooden plank. The German sergeant, Paul Bush again, runs up to the boat but uses no caution, in case there are other mines.
