Continuity mistake: Halfway through the movie, James Caan drives his jeep to escape Nazi brigades and brings his wounded comrade to the hospital. He is wearing full dress, with jacket. After he holds the doctor at gunpoint to "check" his friend, the scene switches outside where he is smoking a cigarette without the jacket, then flashes back with him wearing the jacket. (01:41:00)
Factual error: During the 9th SS Hohenstaufen assault on the bridge, the lead vehicle (the one that gets destroyed first) is a four-wheeled vehicle disguised as an Sd.Kfz .221 armoured car but not the actual vehicle. (01:22:45)
Factual error: As they storm the bridge there is a row of modern sodium street lights prominently visible that didn't arrive until the 70s.
