The tragic ending was thought better for the picture, with something more spectacular than a mere explosion of a powder magazine for the catastrophe. Henry King was for a flood; Robert Haas, art director, for a volcanic eruption. In the end, they had both, also an earthquake—to start the flood. Of course, that meant changing the scene of the story. It was too costly, even for a motion picture magnate, to bring Vesuvius to Rome, so they moved Rome to Vesuvius—that is to say, they moved Angela’s convent to a town on the slopes above Naples, where the volcano would be handy. A laboratory, an important feature in the picture, they likewise built on the Vesuvian slope, but as Vesuvius could not be counted on to erupt on schedule, Haas built a miniature and dependable volcano in the studio.
“We worked very late,” Lillian remembers, “and I can still see Bob Haas, those nights when we were all tired out, sticking his head from the crater of his pet property, with some inane remark that would set us all off in a gale of wild laughter.
“During our stay in Naples, I was given a room in the Excelsior Hotel, with a window that looked out directly on Vesuvius. At that time of year, the sun seemed to rise from the crater. It was a room that Duse had once occupied.
“In Rome, our studio was on the outskirts. From my dressing-room, I could see the dome of St. Peter’s in the distance. We ate our luncheon in a little detached house, where the caretaker and his wife lived. The room was small, and all gathered round one table ... simple food, spaghetti, sardines, cheese, and always red wine with water. And then the Italian bread! A sandwich of Italian bread and sardines, with red Italian wine—nothing is better than that! We named our projection-room ‘The Catacombs,’ for it was a kind of cave, and had the same atmosphere. Our studio being small, we occupied every corner of it.”
Soon after the first of the year, they began “shooting” the picture. They had trouble at the start, getting extras, and workmen. Italians will not drop what they are doing and come to a stranger, even at double price. Finally, when they decided that the picture-makers were reliable—and sane—they came in droves, and remained.
