Corrected entry: It is typical for English-speaking actors trying to speak German, but still noticeable: With his thick accent, speech rhythm and choice of words in his 'perfect German' ("Meine Uhr muß zu langsam gehen" - 'My watch must be going too slow'; in German you would say:"Meine Uhr geht wohl nach"), Mallory would have had his crew caught much faster than he could say 'Hey.'

Corrected entry: In the scene near the beginning of the movie, just after the team gets to the top of the cliff, the German soldiers are put on alert and head out to the cliff. As they leave the compound, one of the German trucks proudly displays the "Dodge" name on the tailgate. An American vehicle with German decals.
