A type of war film which deals with resistance fighters, notably the European guerilla fighters or the undergrounds of World War II. Often the focus is on the tension experienced by the resistance secretly mounting a counterattack against enemy forces without tipping off spies or soldiers. The British film Pimpernel Smith updates the "Scarlet Pimpernel" legend for World War II. The Polish resistance movement was highlighted in Andrzej Wajda's war trilogy (Kanal, Generation, and Ashes And Diamonds), playing on the similarities of Nazi occupation and the iron hand of communism; and many Hollywood war-action pictures used the resistance as fodder for wartime adventures.
