The Hong Kong Film Archive’s search tool is an invaluable resource when you’re faced with the task of translating movie titles that may not be well-known enough (or involve enough Internet-savvy westerners) to be listed in the Internet Movie Database. It’s also great for finding out the standard English names of tiny production companies and major production staff, as well as Chinese translations of foreign movie titles.
After spending hours combing the Internet for obscure movie titles and common transliterations of the names of particular crew members for use in director bios and other festival materials, this will be the first place I’ll look from now on. It’s not perfect, but it’s a great starting place.
