Hungarian Kiraly M43 SMG in the movies

[Scout]

I was just watching this movie about the capture and interrogation of Eichmann, when suddenly up popped what looked like two Hungarian Kiraly designed M43 SMGs in wartime Budapest.

(They look like the folding stock M43 as opposed to the fixed stock M39).

I was very impressed. So very often does the movie industry throw some anachronistic or otherwise wrong arm in there.
Did the movies get it right for once or am I barking up the wrong tree?

An old post but the first time I have seen it-if the film was shot in Hungary or similar Eastern European locale it may just have been what was in the studio prop gun library-as the 9mm Mauser round the SMG uses would have made them rapidly obsolete as live firing weapons post war, perhaps they were more readily available for film work?
