A platoon of American soldiers are sent on a mission to a Pacific Island to eliminate any Japanese resistance ahead of the Allies occupying it as a base for a massive invasion.
36 Hours of Hell is another Euro war movie or more specifically a Macaroni Combat film. It came out in the late 60's heyday of this Italian sub-genre. This is one of the rarer ones which was set in the Pacific theatre of war, as most others took place in Europe or the North African desert, most probably for budget reasons. I've found the films from this genre to be by in large pretty mediocre on the whole, with not a huge amount to make them overly memorable. This one falls into this category too, although it's probably one of the better ones I have seen. It has some decent action scenes, while the narrative told from the perspective of three protagonists - an American captain, a Japanese major and a war journalist – was varied and interesting enough to hold my attention from the most part. All-in-all, this is a pretty typical entry for this type of thing, so I expect those with a taste for it will enjoy it well enough.
