God-awful!!
I saw this again recently, and remember when I first saw it as a premiere on UK TV during the early '80s. A number of these Euro flops were heralded as big films coming soon etc, but I certainly never heard of 'em. They often starred big names who were well past their sell-by. Telefon with Charles Bronson was another one that springs to mind. Considering the length of the movie, certain characters are just sketchy cyphers. We don't learn that much about Ava Gardener, besides that she likes a drink and young toy-boys. And why were there only three people in the IHO control room? In order to maintain secrecy?
I don't really care to be honest.
