Tupamaros! is a radical documentary about a left-wing revolutionary group famous for political kidnappings with the goal of educating their captives to the social realities of the poor and oppressed in Uruguay. But also featured is a sequence on the kidnapping and execution of United States AID official Daniel Mitrione, the event upon which Costa-Gavras' State of Siege was based. "Tupamaros! offers an inside view of this most effective and influential of urban guerrilla movements and of the conditions which prompted its formation. Shot jointly by Swedish director Jan Lindqvist and the Tupamaros themselves, the film had to be smuggled out of the country as a guerrilla action. The very nature of these images invites a sense of complicity, of watching privileged footage... (Yet) the film shows the same virtues of restraint and intelligent organization that mark the movement itself" (Elisabeth Weis, The Village Voice).
