Corrected entry: During the execution scene Telly Savalas uses an AK-47 assault rifle to shoot the German officers, the film is set in 1944 as stated at the beginning, but the gun wasn't in production until 1947,hence the name.

Continuity mistake: When Elliot Gould finds a crate in which he thinks there is treasure Sonny Bono tries to pull him out of the building, knocking the lid off the crate. But in the next scene Gould pushes off Bono, and goes back to the crate where the lid is mysteriously nailed down hard again. (01:47:00 - 01:48:00)
Correction: Telly's rifle in the village square ambush was a German MP44 (1944) assault rifle; the AK47 looks very similar and some say the Soviets copied the design of the earlier rifle. See Wiki.
