Frederick Forsyth was my gateway drug to faction: novels based more or less truly on historical incident. You could trust him because he had a long history as a respected and conscientious journalist. And what a way with plot! This story of a 1960s assassination attempt on the despised French President Charles de Gaulle by disgruntled members of the exiled OAS (the militant underground) would seem to have nothing much going for it on the surface: the outcome, for one. But the trick here is brilliant. These patriots hire a British hitman (Edward Fox) who is completely unknown to the authorities. And as he gathers the materiel required for such an audacious once-in-a-lifetime évènement and removes all the human obstacles in his path, we realise, at the foregone but nail-biting conclusion, that we know absolutely nothing about him at all. This is narrative sleight of hand at its best. And it is crucial to the tension that the ruthless professional Jackal remains a complete enigma, a mystery at the heart of a brilliantly staged action thriller with a great supporting cast. His nemesis proves to be a Parisian police detective (Michael Lonsdale) determined to root out this threat to democracy. Adapted by Scottish-American screenwriter Kenneth Ross who would perform the same miracle with The Odessa File. Gripping outing by director Fred Zinnemann who meshes his predilection for documentary-style realism with all the tricks of a cinema of attractions. Flawlessly executed.
