Michael Fassbender’s performance as Lt. Archie Hilcox is layered with irony due to his real life. Fassbender was born in Germany to German and Irish parents and raised in Ireland, now residing in London with fluency in German as his first language and English as his second, and a mastery of English accents and dialects. Here he plays an Englishman who goes undercover as a German, and who can speak German fluently, but cannot hide his accent.
