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.
Escape to Athena (1979)
1 corrected entry
Directed by: George P. Cosmatos
Starring: David Niven, Roger Moore, Telly Savalas, Stefanie Powers
Continuity mistake: Following the shoot out between the Germans and the Greek partisans being aided by the English and American POW's, a German Officer leaps onto a motorbike and takes off into the narrow streets of the village. An American follows on a motorbike and sidecar. Towards the end of the chase the bikes 'jump' over a cart. The German Officer's cap flies off, yet as he tears into a courtyard he has his cap back on.
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.
