I always try to find at least one film at Toronto that's way off the beaten track. I rarely stray further afield than I did Tuesday night, when I found myself watching "Wake in Fright," a film made in Australia in 1971 and almost lost forever. It's not dated. It is powerful, genuinely shocking, and rather amazing. It comes billed as a "horror film," and contains a great deal of horror, but all of the horror is human and brutally realistic.
