a conlang in Bergman's _The Silence_?

Hi all.

So, I was just watching Ingmar Bergman's _The Silence_ again
tonight, and it occurred to me that it's possible that Bergman
had created a conlang for the culture of the country in which
the main characters are staying. The hotel attendant is constantly
mumbling in some (to me) incomprehensible and unidentifiable
language, which is clearly intended not to be understood by
the characters staying in the hotel, either, since they have
to communicate by gesture. The newspapers in the bar in the
movie are also written in some mysterious language that doesn't
resemble anything I've seen before.

I dunno.  I may just know too little Kashubian, or whatever it
is the hotel attendant is mumbling.  But I'm pretty sure it isn't
a real language.  Anyone got any ideas?
