Romain Duris did not receive an Oscar nomination for portraying Cinquanta in All The Money in the World.
Duris even in that scene portrays Cinquanta believable enough as this potentially violent man asking for money, but even in that moment as we see him, though Gail does only hears him, he shows signs that he's probably not as sinister as his hissing voice suggests. This continues as Cinquanta acts as the primary guardian for Getty while in captivity, and again Duris excels in creating this duality within Cinquanta utilizing his voice and his physical performance separately. A great moment with this is when he speaking to Getty from outside of his cell so he can only hear his voice, but we obviously see Duris the entire time. Again Duris delivers Cinquanta's lines possibly with the interpretation of creating fear in the young man as questions why his family hates him so much since they refuse to pay the ransom. Meanwhile Duris physically shows in this moment Cinquanta taking in this idea of a family refusing to this for his son genuinely troubles him, and creating this anguish in his eyes as he thinks about being so rejected that his family would leave him at the torment of his kidnappers. Duris again reveals more of a duality in this as he portrays Cinquanta again attempting the role of the kidnapper through his words, yet the man's thoughts tell a different story. This is more fully exploited when Cinquanta casually walks into the cell exposing his face to Getty. Duris's performance in this scene is essential to the moment as he approaches in exuding just a friendly demeanor and even the moment of the realization Duris plays not as anger towards Getty, but rather a moment of sheer anxiety for potentially his own fate and possibly his hostage as well for this exposure.
Duris quietly realizes in each subsequent scene this gradual reduction of any sort of false intensity, needed for a kidnapper, and slowly begins to reveal this decent man despite himself. This continues as Cinquanta and his family decide to sell Getty to a bigger name in the underworld of Italy, who they decide to keep Cinquanta on as basically a caretaker for Getty. Duris in these scenes, even when he says barely anything, is the most captivating factor. His silent work is remarkable as he so effectively portrays the ever growing concern in Cinquanta as the other men speak of the young man's fate. I love the way Duris reveals, even though there is not a great deal of attention paid to this by the film overall, this conflict in the man. He depicts almost this dual frustration in him that begins more as the man is pained by his inability to be harder than he truly is in heart, that slowly coverts towards itself to not being able to fully be that man he is in heart. Duris though in each scene breaks the walls down on any facade of this vicious thug. In his scenes with Plummer Duris begins to become quite moving actually in showing a more direct warmth and as a well a somberness as he tends to Getty knowing some terrible things may happen to him very soon. Duris does a great deal of heavy lifting here as I found Duris's performance made me care more about John Paul III than Charlie Plummer's performance.
Duris keeps this direct concern alive, and brings a real needed emotion to the tension of these scenes. Duris is fantastic as he begins to make it that even in his phone calls, where Cinquanta could most easily put on the kidnappers act, he now reveals his concern. This is to the point that Duris in the later calls brings the urgency in every word almost to the point as though he's the one attempting to ensure Getty's release. In a way he is and it is marvelous the way Duris so naturally realizes this transition. One of the best scenes in the film is Getty's ear amputation, which is a infamous moment in the actual case, but the reason for this again is Duris's devoted work to the idea of Cinquanta's concern for Getty. Duris is again oddly enough far more heartbreaking than Plummer in this scene by showing how much the act is tearing apart the man in watching while at the same time still so earnestly projecting such a warmth as he talks him through the "surgery". In every scene Duris is genuinely affecting by quietly portraying this sympathy that only gets stronger. I love the moment where Getty almost escapes, and Duris delivers just this subtle bit of joy in the moment hoping that he has been successful. The idea that the kidnapper goes from one of the people putting a bag over the young man's head to attacking another man to save the kid is a bit farfetched. Duris manages to overcome this rift in the suspension of disbelief by so honestly and effectively portraying every step of this transformation by showing to be more of this revelation of the man's true self throughout. This is a great performance, and it is an utter shame that it has been barely given a mention around the film since honestly Duris is the best part of it.
