Did you know that Die Hard was based on the Roderick Thorp novel Nothing Lasts Forever, which was a sequel to his earlier novel The Detective? Nothing Lasts Forever was set in a Los Angeles skyscraper besieged by German terrorists during a Christmas Eve office party, and followed a retired NYPD detective who was there visiting his daughter and managed to slip away undetected and barefoot. Joe Leland, the character from the books who became John McClane in Die Hard, was portrayed by Frank Sinatra in the film adaptation of The Detective, so Frank Sinatra and Bruce Willis played different versions of the same character. That's my Christmas trivia post for the day. 😊
