WELLINGTON.- After a world-wide search, a large part of The White Shadow (1923), thought to be the earliest surviving feature by Alfred Hitchcock (1899-1990), the celebrated master of suspense has been found in New Zealand – just in time for the filmmaker’s 112th birthday. A wild, atmospheric melodrama starring Betty Compson in a dual role as twin sisters, one angelic and the other “without a soul,” the lost film turned up among the cache of unidentified American nitrate prints safeguarded for the last 23 years by the New Zealand Film Archive. So far, only the first three reels of the six-reel feature have been found; no other copy is known to exist.
