The giveaway also appears in the closing credits with blooper reels showing the characters, real and fictitious alike, laughing over their lines or over their inability to remember them. But there is a final trick here, a "hoax within a hoax": the real characters are shown joking, giving the false impression that they are voluntarily part of the hoax. In fact at least one of these "jokes" - Kissinger saying that he would do it all over again - appears in "Les hommes de la Maison Blanche" where he turns out to be actually talking quite seriously about the war in Vietnam.
