overnight before catching the plane to Sydney. But his one night stretches
to five and he plunges headlong toward his own destruction. When the

Another "lost" film was Australia's "Lost in Fright". A copy was known
to exist in Ireland but it was in such poor shape that no VHS or DVD
release could be made from it.  The films editor spent ten years looking
for a better copy. He eventually found a negitive in the States in a pile
labeled "For Destruction" and was able in time to restore it. (wikipedia)
