Von Ryan's Express is a 1965 World War II adventure film starring Frank Sinatra, Trevor Howard, and Raffaella Carrà, and directed by Mark Robson. Produced in CinemaScope, the film depicts a group of Allied prisoners of war (POWs) who conduct a daring escape by hijacking the freight train carrying the POWs and fleeing through German-occupied Italy to Switzerland. Based on the 1964 novel by David Westheimer, the film changes several aspects of the novel, most notably the ending, which is considerably more upbeat in the book. Financially, it became one of Sinatra's most successful films.
