Bo Widerberg's vision of Swedish cinema parted radically with its contemporary form. He called for a greater political significance and more progressive story telling. The leading figure of Swedish cinema at the time, Ingmar Bergman, was not Widerberg's ideal at all, although he recognized his position: "Neither I nor my friends saw very much in him. We didn't find the issue of god's existence that damned important. But it's safe to say you'd be putting yourself in a bad position if you're trying to slit the throat of the father figure before your own debut." In his book, A Vision of Swedish Cinema, Widerberg concluded that Bergman's films almost exclusively dealt with issues between people directed upwards and seldom sideways. According to Widerberg, Bergman made vertical films when the need for horizontal ones was more dire. On the other hand, Widerberg wanted film to be a tool of the social sciences, a kind of sociological report.
