- Creator Breakdown: Rupert Friend struggled throughout filming and became increasingly withdrawn after shooting some of the more harrowing scenes.
- Deleted Scene: Involving Bruno and one of his friends encountering a Jewish man right before he is captured. This is presumably Pavel from the book.
- Enforced Method Acting: When rehearsing the scene where Lt Kotler asks the boys if Shmuel was stealing food, Rupert Friend merely raised his voice when he was supposed to shout his lines. Once they actually filmed the scene, the boys were genuinely startled by his sudden shouting.
- Fake Nationality: The majority of the cast are British using their own accents to play German characters. Vera Farmiga is an American playing a Fake Brit.
- Shown Their Work: Bruno's mother is seen wearing her wedding ring on her right hand, as is the German tradition.
- The Wiki Rule: The book/film has a small one.
