Question: What are both Erich von Stroheim and Sidney J. Furie?
Context: Sidney J. Furie (born February 28, 1933) is a Canadian film director, screenwriter, and producer best known for his extensive work in both British and American cinema between the 1960s and early 1980s.  Like his contemporaries Norman Jewison and Ted Kotcheff, he was one of earliest Canadian directors to achieve mainstream critical and financial success outside their native country at a time when its film industry was virtually nonexistent.  He won a BAFTA Film Award and was nominated for a Palme d'Or for his work on the acclaimed spy thriller "The Ipcress File" starring Michael Caine. San Francisco is a 1936 musical-drama directed by Woody Van Dyke, based on the April 18, 1906 San Francisco earthquake.  The film, which was the top-grossing movie of that year, stars Clark Gable, Jeanette MacDonald, and Spencer Tracy.  The then very popular singing of MacDonald helped make this film a hit, coming on the heels of her other 1936 blockbuster, "Rose Marie".  Famous silent film directors D. W. Griffith and Erich von Stroheim worked on the film without credit.  Griffith directed some of the mob scenes while von Stroheim contributed to the screenplay. Erich von Stroheim (born Erich Oswald Stroheim; September 22, 1885 – May 12, 1957) was an Austrian-American director, actor and producer, most notable as being a film star of the silent era, subsequently noted as an auteur for his directorial work.  He died in 1957 in France, at age 71. Hello, Sister!  is a 1933 American pre-Code drama film directed by Alan Crosland, Erich von Stroheim, Raoul Walsh, and Alfred L. Werker.  It is a re-edited version of von Stroheim's now-lost film Walking Down Broadway.  "Hello, Sister!"  was itself thought to have perished as well, until a print was found in the 1970s. The Wedding March is a 1928 American silent romantic drama film written and directed by and starring Erich von Stroheim.  It also stars Fay Wray and ZaSu Pitts.  Paramount Pictures forced von Stroheim to create two films from the footage, the second being "The Honeymoon" (eventually re-edited back into one film for a re-release).  "The Honeymoon" is now considered lost, the only known copy destroyed in a fire in France in 1959. Under Secret Orders, also known as Mademoiselle Doctor, is a 1937 British spy film directed by Edmond T. Gréville and starring Erich von Stroheim, John Loder, Dita Parlo and Claire Luce.  It is an English-language version of the French film "Mademoiselle Docteur", also known as "Salonique, nid d'espions", and released in the United States as "Street of Shadows", which was filmed at the same time under the direction of G. W. Pabst.  Both films have exactly the same plot, but there were differences in the cast between the two: in particular, von Stroheim was not in the French version. I Was an Adventuress is a 1940 American drama film directed by Gregory Ratoff, starring Vera Zorina, Richard Greene, Erich von Stroheim and Peter Lorre.  Actress/ballerina Countess Tanya Vronsky (Vera Zorina) works as decoy for two international con artists Andre Desormeaux (Erich von Stroheim) and Polo (Peter Lorre). Foolish Wives is a 1922 American silent drama film produced and distributed by Universal Pictures under their Super-Jewel banner and written and directed by Erich von Stroheim.  The drama features von Stroheim, Rudolph Christians, Miss DuPont, Maude George, and others. Blind Husbands is a 1919 American drama film directed by Erich von Stroheim.  The film is an adaptation of the story "The Pinnacle" by Stroheim. Cinema 1: The Movement Image (French: "Cinéma 1.  L'Image-Mouvement" ) is a 1983 book by the philosopher Gilles Deleuze, in which the author combines philosophy with film criticism.  In the preface to the French edition Deleuze says that, "This study is not a history of cinema.  It is a taxonomy, an attempt at the classifications of images and signs" and acknowledges the influence of the American pragmatist C. S. Peirce and the French philosopher Henri Bergson (p. xiv).  The cinema covered in the book ranges from the silent era to the 1970s, and includes the work of D. W. Griffith, Abel Gance, Erich von Stroheim, Charlie Chaplin, Sergei Eisenstein, Luis Buñuel, Howard Hawks, Robert Bresson, Jean-Luc Godard, Sidney Lumet and Robert Altman.  The second volume, "Cinéma 2, L'Image-temps" was published in 1985 (translated as "Cinema 2: The Time-Image" in 1989).  Both books are clearly about cinema, but he also uses cinema to theorise time, movement and life as a whole.
