A few days before shooting began a press conference was held with all the pomp and circumstance which was "only normally reserved for royalty or heads of state", according to one reporter. Having assured himself that everyone could hear properly, Bergman went up to a blackboard and wrote: PERSONA. 'Does anyone know what this is?' No answer was forthcoming from the press. 'You see', Bergman went on, 'the film might not have a name at all. First of all I suggested to Kenne Fant (at SF) the title Cinematography?' but that made Kenne sad. 'Terrible name', thought Kenne. So I came up with this title, 'Persona'. 'Any name's better than cinematography', said Kenne, and approved my proposal. Bergman then went on to explain that 'Persona' is the Latin name for the face masks worn by actors in antiquity. 'It's an amusing title, a good name, an apt name. The film will be about people's masks and attitudes.' Bergman also mentioned that the film would be shot in standard format in black and white, 'which I think is the most beautiful.'
Most of the shooting took place on Fårö but began with some work in the studio, Filmstaden, starting on 19 July 1965. 'The first days were nightmarish. All I felt was: 'I can't manage this!' and one day after another went by, and all the time we got only bad results, bloody awful results. And Bibi was angry and Liv was nervous, and I was paralyzed with fatigue. 'When they arrived at Fårö, the atmosphere was much improved and work proceeded more smoothly.
Sven Nykvist was faced with new challenges. The close-up in the opening sequences of an old film projector with carbon rods that meet together was not an easy shot to achieve. While Nykvist was shooting Mai Zetterling's Loving Couples (Älskande par, 1964) he worked on this sequence in his spare time: "the studio manager was annoyed because I was using up so much raw film outside the regular budget even before shooting had begun."
Bibi Andersson had acted in most of Bergman's films since Smiles of a Summer Night, with the notable exception of the 'trilogy' (Through a Glass Darkly, Winter Light and The Silence). The roles she had played were important yet relatively minor. Persona was to be her tour de force. On one occasion Bergman said of Andersson that she needed to believe in something before she could act it. This might sound like a limitation, yet in Bergman's eyes it was a sign of integrity. One example of this in Persona is Alma's famous monologue about a sexual adventure she once had on a beach with another woman and two young boys. During the shooting Bergman wanted to scrap the scene, perhaps because he thought it was too explicit. But Andersson insisted that they keep it in:
"I said, 'Let me shoot it, but let me just alter certain words no woman would ay. It's written by a man, and I can feel it's a man. Let me change certain things.' He said, 'You do what you want with it. We'll shoot it, and then we'll go and see it together.'" Shooting the scene was embarrassing, yet Bergman was pleased with the result. There was just one thing, though: "something's wrong with the sound", he claimed. He asked Andersson to speak the monologue again alone in the mixing studio. The sound would be synchronised afterwards. The sound problem was probably just a ruse: originally she had spoken in a high, girlish voice and been satisfied with that, but when she subsequently dubbed the scene alone she used a much lower tone, something she only dared to do when nobody was watching or listening. Later she expressed the view that the intimate quality of the scene was largely down to this re-take.
For Liv Ullmann, a few years younger than Andersson, this was her first Bergman film. Many more were to follow: she played leading roles in nine films up to and including Autumn Sonata. The largely silent role of Elisabet also marked the start of a highly successful international career.
The most famous image from the film is that of an extraordinary face, half Ullmann's and half Andersson's. According to Bergman, "In most people one side of the face is more attractive than the other, their so-called good side." The two images that Nykvist spliced together "showed their respective bad sides." When the film came back from the laboratory he asked both the actresses to come to the editing room. "Bibi exclaims in surprise: 'But Liv, you look so strange!' And Liv says: "No, it's you Bibi, you look very strange!"
The film's unit manager, and the photographer of a number of remarkable stills from the shoot, was Bo Arne Vibenius. Some years later he directed a film that was banned in Sweden: Thriller – a Cruel Picture (1974), recently revealed as an important source of inspiration for Quentin Tarantino's Kill Bill.
The original score was by the composer Lars Johan Werle, best known for his operas including Dreaming About Thérèse (Drömmen om Thérèse, 1964) and The Journey (Resan, 1970). His previous film scores included the music for Alf Sjöberg's The Island (Ön, 1966). He had also composed the music for Sjöberg's Royal Dramatic Theatre production of Euripides' Hippolytus (1965), where he first met Bergman, then head of the theatre. Bergman's brief was precise: he knew exactly what he wanted. These limitations on his artistic freedom did not trouble Werle, who was extremely positive about working with Bergman and did not feel unduly restricted by his demands.
