This is a very under-rated film which sets off at a good pace, and gathers momentum as the story progresses. As suspense thrillers go, it's hard to beat, and is helped in no small way by terrific playing from a top class ensemble cast. Special mention must go to Richard Attenborough as the oily, sly grass. Attenborough simply oozes slime in the role, and demonstrates yet again what a very fine actor he is. Pier Angeli, Eddie Constantine and John Gregson are all uniformly excellent as well. It's a film that never seems to receive regular airings, which is a pity as it is well worth seeing and is highly recommended. The location scenes are good, and the direction and cinematography are first rate too. The film really is a long lost gem!

I most certainly agree with the reviewer who awarded the film a "10". It does, indeed, well deserve it.It is one of the most underrated pictures around with good, strong performances, very taut direction by Guy Green, excellent photography by Wilkie Cooper and interesting locations in the Canary Islands. Also worthy of note is the music score which was by the great French composer, Georges Auric.Just as good, of course, is the story. I wont, of course, give away its great plot but just simply advise people to see it whenever it turns up. I envy the person who bought it on ebay! I, too, hope he enjoys it. It's a must-see thriller of the first order.

I saw this when I was about seven years old from the back of our car at a drive in movie. I thought it was a very exciting movie at the time but that was the only time I saw it, and would like to find a copy of it. I have not been able to find it in DVD or VHS yet, if anyone knows where it is available, please let me know. This movie has an Alfred Hitchcock feel to it, the suspense slowly builds to a climactic ending. I am surprised that it is not more well known as I have found few references to it on the internet. Most of the actors are not familiar to me except for Richard Attenborough whom I also enjoyed in "The Great Escape".

I give this film 10 stars because it deserves 10 stars. Pier Angeli was charming and showed that she was very much like her character. Her character was the heart of the survivors of a plane crash that are left to try to survive on an island that could be set to blow up. Richard Attenborough was very convincing as the character who will stop at nothing to get off the island. His tenacity was evident in that role.My favorite scene is when Pier Angeli's character goes into the water to save one survivor from drowning. This shows her character's heart and strength. She couldn't have played this role any better.I wanted others to see it so I sold it on Ebay. I hope the person I sold it to sells it to someone else and so on and so on.
