Investigación sobre un crimen perfecto

I found this very disappointing. Seemingly set in London this proceeds rather woodenly like some minor Agatha Christie. But it is not London and apart from some travelogue footage to suggest so, most was shot in Italian studios. This I think added to the film's problems as there seems to be a lack of belief in the material and also necessitating so many sequences to be shot in the dark so as not to give things away. I had a false belief that if all else failed there would always be Gloria Guida to look at but she is all but wasted here. Joseph Cotton does his best as does a rather stuck up seeming, Janet Agren and we get unintentional or not humour from the butler and his English accent. As for the tale of various directors competing for the number one job, it all gets a bit silly and we are left wondering why the Agren character puts up with her ancient and yet philandering husband if she has all the money.
