The "official" title of this film is Hemingway's Adventures of a Young Man; its screenplay is adapted from semi-autobiographical "Nick Adams" stories written by Ernest Hemingway. Played by Richard Beymer (West Side Story), Nick Adams is a young Michigan boy who sets out in the early 1900s to learn about life and to pursue a journalistic career. No sooner is he on his way than he gets his first taste of "real life" by being thrown off a train by a railroad agent. He attempts to secure newspaper work, but is laughed out of the office due to his inexperience. He gains valuable insight on the human condition while serving in the Italian army during World War One, where (in Farewell to Arms fashion) a star-crossed romance develops between Nick and a Red Cross nurse (Susan Strasberg). Nick returns to America determined to pursue his destiny by writing of his now-vast experiences. Long and somewhat poky, Adventures of a Young Man is enlivened by the cameo appearance of Paul Newman as a pathetic, punch drunk boxer.
