Flame & Citron

Flame & Citron is a 2008 historical drama film co-written and directed by the Danish director Ole Christian Madsen. The film, a fictionalized account based on historical events, stars Thure Lindhardt and Mads Mikkelsen as two Danish resistance movement fighters nicknamed Flammen and Citronen, during the Nazi occupation of Denmark in World War II. Attracted by the story of the pair since he was twelve, Madsen spent eight years along with co-writer Lars K. Andersen researching historical archives to produce it.
