"Perhaps the game has gone too far."
Two years after Carlos Mandel died in a plane accident over the English Channel, his widow, Lisa (Patty Shepard) gathers twelve friends, relatives and acquaintances for a weekend at her remote estate. But at dinner on the first night, she reveals her true intentions - she believes that her husband was, in fact, murdered and that one of her guests is the killer. Accusations and whispers fill the next few days as the guests speculate. Was Carlos killed over money or revenge or jealousy? Could the killer be flirtatious playboy Harry Stephen (Simón Andreau), Arlen, the art forger ( Jack Taylor) or even Lisa's own aunt, Bertha (Trini Alonso)? As secrets are revealed and the killer becomes cornered, the guests start turning up dead. Can the survivors unmask the killer and escape before they're all killed off?
The Killer is One of Thirteen (not to be confused with The Killer Reserved Nine Seats) is another giallo based on the Agatha Christie model, much like The Weekend Murders, Nine Guests For a Crime and Death on the Fourposter. As far as gialli go, this one isn't a great entry - no nudity, very little blood, it's set in a large but frumpy mansion, and the murders don't start until nearly an hour in. But it does feature some favorite giallo actors including Simón Andreu and Paul Naschy.
- One of the eight murders listed above - Carlos's plane crash - occurs before the action of the movie starts.
- A better translation of the Spanish title might be "The Killer is Among the Thirteen."
- The title "sort of" makes sense because while the suspects include Lisa and her twelve guests, suspicion also falls on Lisa's butler, chauffeur, maid and gardener, bringing the list of suspects to seventeen.
I am now more sure than ever that Paul Naschy refused to appear in a movie unless he got to be in a fight scene.
After the first two guests are murdered it's revealed that the culprit also cut the phone lines and sabotaged all the guests' cars, so there could be no escape. Everyone is worried, but they agree to lock themselves in their rooms until the police show up. But how would the police know to come if the phone lines are down?
First, I want to point out this miniature study in fashion contrasts: boorish businessman Jorge seated next to free-thinking artist Arlen.
Next, I want to point out Mrs. Martin's wacky floral daywear.
But the real fashion star of the movie is Cecilia Paroli (Doris Coll). While most of the other women are decked out in bold, garish prints, she always keeps it classy with an understated yet elegant wardrobe.
