(as far as I remember, the extras suck, the "about the movie" and "actors/director profiles" are simply a text information, but it's just a basic version, you can't expect much, except the movie itself, for 12 złotych, I could check it, I have the DVD, but it's downstairs and I don't wanna wake up my family, it's 4 a.m. here, so if you insist, I could do it tomorrow, but I'm almost sure, it's just the movie and no interesting extras).
