This polaroid was made during shooting Robert Altman's "Fool for Love". Robby Muller only shot the first 9 days of the film after he got replaced by another cameraman. Robert Altman said the following about his (short) experience of working with Robby Muller:

“For the last ten years, I’ve been working with two Canadian cameramen, Pierre Mignot and Jean Lapine. I shot a film called Fool For Love, on which Robby Müller was the cameraman because those guys weren’t available at the time and I had to start. And he’s a great cameraman. I mean, really a great cameraman. And we got down to New Mexico and started shooting, and suddenly I’m seeing these beautiful pictures, and I don’t know how to make this kind of movie. And I stopped after nine days, and I said, ‘You know, we have to get divorced.’ I said, ‘You’re making a beautiful movie. I don’t want a beautiful movie.’ And by that time, Pierre was finished, and he came down and shot it. And it’s a terrible thing to happen. But there was no communication about what we both wanted. We were just making two kinds of movies.”
