I remember seeing it in theaters as a kid. It was all subtitled, so I had to be of reading age, so it had to have come out somewhere in the late 90’s to early 2000’s.

The movie centered around a young boy during WWII. My memory is hazy but I think I remember him peeing himself and his mom’s boyfriend chastising him about it. I also remember him meeting up with some other boys, and the boys fired off a bullet with a nail and hammer.
I think the mom’s boyfriend died at the end of the movie, I’m not sure, the young boy might have killed him.

I think the film was in polish or in one of those other Nordic, Slavic, or Germanic languages. I could be wrong about that too..

I can’t for the life of me remember the title so if anyone could help me that would be amazing!!
