E' stato tratto un film: The President Vanishes (Strange Conspiracy) Trama del film: The book concerns the mysterious disappearance of the President of the United States, who was facing a serious political crisis, perhaps even impeachment, over his handling of a foreign situation, namely the impending war (what we would now call World War II). The disappearance of the president seems like a kidnapping, but no ransom is demanded. Although not revealed in detail until near the end, it is fairly apparent from an early stage that the president has staged his own disappearance to counter an impending military coup staged by an upstart army of fascist "grey shirts" allied with a small coterie of industrialists (similar to the Business Plot). The aim of all this is to involve the United States in a European war when none of the combatants has attacked American territory.
