Roger directed for two days on a set left over from a previous production, and without a proper script. He hired Francis Coppola to write a script and finish the picture. After five weeks of shooting, Roger fired Francis, and hired me to finish the picture. Jack Hill was hired to write a new script with me. A lot of what Francis shot was thrown out, except for the stuff with the witch from WIZARD OF OZ. (Dorothy Newman), and I finished the picture in five days of shooting. All of the interiors are Roger's (with the exception of Francis's witch's lair), and most of the exteriors are mine. To the best of my recollection, and contrary to legend, Jack Nicholson did not direct any of the film.。
