The Day of The Jackal author Frederick Forsyth revealed he sold the film rights to his 1971 bestseller decades ago for just £20,000 (around $25,000) and will get next to nothing from the new $126,000,000 TV adaptation. 'The new adaptation has paid him a modest fee for the title. "It wasn't out of obligation," he said, "it was a gesture."
Frederick Forsyth was working as a freelance journalist covering the Biafran War. When it ended he returned to Britain, unemployed and unsure what to do next. He said: 'I came back Christmas '69, thoroughly skint. I don't have a likelihood of a job, don't have a flat, don't have a car and don't have any savings. Then I had this crazy, crazy idea to write a novel. 'Everybody said you must be joking or mad because the chances of even getting it published are hundreds to one, even thousands.' Within weeks of publication, the film rights were snapped up. Some of Hollywood's biggest stars battled to play the Jackal in the 1973 film but the role went to the then unknown Edward Fox because director Fred Zinnemann thought he could pass invisibly in a crowd.
Ulle Dag Charles is an anagram for Charles de Gaulle, the assassination target in the original novel, and is known by the initials UDC in the same way De Gaulle is often referred to as CDG.
The Jackal is seen driving a white Alfa Romeo Spider. In El día del chacal (1973), The Jackal also drives a white Alfa Romeo, albeit an earlier model.
The scene where the Jackal test fires his new rifle, using a watermelon that's been painted is a direct reference to El día del chacal (1973) where Edward Fox's Jackal test fires his new rifle using the same target.
