With the coming of the “Four Horsemen of the Apocalypse” to the Capitol next week, Rex Ingram will have two pictures running simultaneously on Broadway. In creating this stupendous production, this young director has made one of the great classics of the screen. The picture, adapted by June Mathis from the novel of Vincente Ibanez, is not a war play, except as the war serves as a background for the story teeming with dramatic passion. The director has succeeded in concentrating the great struggle in a series of unforgettable pictures that flash out the quintessence of life. Through it all is the deeply human, deeply moving spectacle of intensely real people in their baffled attempts to readjust themselves to the demands of the war days. In the cast of 50 principles and 2500 extras are included a score of well-known screen stars. They are Rudolph Valentino, Alice Terry, Pomeroy Cannon, Joseph Swickard, Brinsley Shaw, Alan Hale, Bridgetta Clark, Mabel Van Buren, John Sainpolis, Nigel de Brulier, Virginia Warwick, Derek Ghent, Stuart Holmes and Edward Connelly. SL Rothafel and his staff are at work on the details of a presentation in keeping with the production.
