'The Girl from Petrovka' trivia and fun facts

Before filming started, Anthony Hopkins scoured the bookshops of London's Charing Cross Road trying to find a copy of the novel by George Feifer, upon which this film was based. He had no luck and went to catch a train home. There at the station, lying forgotten on a bench, was a copy of the book. Years later, Hopkins met Feifer, who told him that he had lent his own copy to a friend, who then lost it. Hopkins produced the one he found and asked if it was his. By an amazing coincidence, it was the author's own book Hopkins had chanced upon.
