Newcomer Asa Butterfield stars as the young Bruno, son of an SS Officer (palyed by David Thewlis, Harry Potter) who is stationed at a Nazi concentration camp. Bruno's family includes his mother (Vera Farmiga, Nothing But The Truth) and his sister Grettel (played by Amber Beattie who's also in her first major role).
From his window Bruno notices a "farm" with people wearing "striped pyjamas". There he meets a boy named Shmuel (played by Jack Scanlon who again is new) and they become friends. Another key character is Lt. Kotler, a young SS officer played by Rupert Friend (The Libertine).
The movie has an interesting story, and is well done.
Rated 14-A (ONT)* PG-13 (USA) Overall a good movie
P.S. Spoilers: I was left wondering if the father really did get the point? That what they were doing was evil? Or was he just sad because his son died?
*I couldn't find this so that is my best guess, though it could be PG
