City on Fire, a disaster thriller filmed in Canada with dialogue in both French and English, tells the story of an oil-refinery explosion in a small town. Dr. Frank Whitman (Barry Newman) and his co-workers, including Nurse Harper (Shelley Winters) and Dr. Matwick (Donald Pilon), fight bravely to save the victims even when they, themselves are endangered by the fire. The film also features cameos by Ava Gardner and Henry Fonda. The film moves at a fast pace and creates a great deal of suspense as the fire closes in on the survivors. Director Alvin Rakoff uses creativity instead of a big budget and, aided by the splendid cinematography of Rene Verzier, succeeds in creating an exciting disaster film.
