Ocho sentencias de muerte

Sir Alec Guinness nearly drowned in the scene where the Admiral goes down with his sinking ship. Guinness was held down by wires whilst the set filled up with water. Once the scene was wrapped, the crew started to leave, until one technician suddenly realized that they had forgotten to release Sir Alec from the wires holding him underwater. He immediately dove into the waters with some wire-cutters and freed Guinness. Fortunately for all concerned, Guinness took great pride in his ability to hold his breath for long periods of time.

The first murder that Louis Mazzini commits involves him swimming fully dressed underwater to release a boat from its moorings. In spite of having brought no change of clothes or even a towel, he is shown shortly after committing the murder paddling down the river with his clothes bone-dry.

The opening credits list photos of the 4 leading actors with their character names; in the case of Alec Guinness, 8 photos of the 8 characters he plays are shown, along with the one character name of "The D'Ascoyne Family." In the end credits, the 8 character names are listed for him.
