Credit for directing this film was given to James Cameron. Most of the work was actually performed by Ovidio G. Assonitis, the film's producer and prolific film-maker. Assonitis was dissatisfied with Cameron's progress after the first week and took over. According to "Dreaming Aloud," a biography of James Cameron by Christopher Heard, Cameron did do the shooting for this movie, but was not allowed to see his footage and was not involved in editing. He broke into the editing room and cut his own version, but was caught and Assonitis re-cut it again.
It was during the Rome release of this movie in which James Cameron grew ill and had a dream about a metallic torso dragging itself from an explosion while holding kitchen knives, which gave Cameron the idea for The Terminator (1984).
