If one notices similarities between this saga and Jean-Pierre Melville’s “Army of Shadows,” there is justification, as the Melville work served as an inspiration for “Flame & Citron.” But whereas the Melville film was icy in its tone, this one tips more toward conventional adventure filmmaking. Accordingly, one can question whether this or that situation could have really happened as depicted, but the overall impact doesn’t leave much time to spend on such calculations. The action and the willingness to risk one’s life for the greater cause dominate.

Thure Lindhardt as Flame and Mads Mikkelsen as Citron—these are their underground names—are excellent in their portrayals of the resistance team. They have different personalities, but are united in their dare-devil determination to wipe out the Nazi enemy and are ready to die if necessary. The screenplay presents one dangerous situation after another, complicated by the knowledge that there is a traitor in their midst. The suspicions thus cast present the nasty task of being willing to identify and eliminate an enemy within.
