I saw this film in 1970 or 1971 in New York and have remembered it ever since. We came in late to a double feature and didn't see the title--I have been unsure of it all these years. It features impressive battle scenes, a heart-wrenching love story and beautiful cinematography. It is also the first film I ever saw that depicted medieval Japanese culture in all its glory. The beautifully photographed compound of the shogun is, by itself, worth the price of admission. There are many interior shots, showing beautiful rooms with sliding screens that figure in the plot. Now I would dearly love to see Gate of Hell again, but apparently it is not available on DVD. Criterion, here is a worthy quest for you!!
