Black Book
Paul Verhoeven, 2006, Holland (8.8*)
Excellent true story of a Jewish double agent, who went so far as to die all her hair blonde so she could literally sleep with the Nazi enemy in World War II Holland. She did this after nearly escaping, only to have Germans kill nearly everyone on aboat while she escapes, and being rescued by the underground. Carice von Houten plays a singer who infiltrates local Gestapo headquarters by seducing officers.
This is a strong storyline, with some excellent war sequences, a modernized version of an early 40's war film. This film was largely ignored in the U.S., grossing just 4m, but has a rating of 8 at IMDB, making it borderline top 250 all-time, and won 11 awards overall, including best film at the Netherlands film festival.
Verhoeven excels at films about WW2 Holland, as his breakthrough international success was Soldier of Orange, which made Rutger Hauer an international star.
