Black Book (2006)
This Dutch World War II film stars Carice van Houten as Jewish spy Rachel Rosenthal. Working for the Dutch resistance, Ronsenthal seduces a German officer to get inside the local Nazi intelligence organisation – and, promptly falls in love with him. With wartime gadgetry and double agents, Black Book is proof that you don't need hi-tech kit to be a spy.
Director Paul Verhoeven – the man behind Robocop, Starship Troopers and, er, Showgirls – actually lived through the Nazi occupation of the Netherlands, lending a touch of versimilitude to Black Book that sets it about as far apart from his earlier work as it's possible to get.
