Following the success of "Hotel", Hailey moved to California. In 1968 he achieved international fame with his fourth novel, "Airport" (Doubleday), the story of one eventful night at a midwestern international airport. The novel was No. 1 in the "New York Times" for 30 weeks, and became the top-selling novel of the year. The film adaptation, released in 1970, was the second-highest-grossing film of the year (second only to "Love Story") and received ten Academy Award nominations, including best picture. The success of the film, together with that of 1972's "The Poseidon Adventure", led to the proliferation of "disaster films" during the 1970s, which included three additional films in what became the "Airport" franchise.
