Bergman believes that a novel cannot be put into a film completely. It becomes a complete injustice since the novel helps in triggering the intellectual faculty of a person whereas the film helps in triggering the emotions, directly. Bergan believes that the individual effect of each of these two art forms on the audience is starkly different from each other.
However, according to Umberto Eco, the film takes over the popularity of a novel.E- co believes that the novel reaches the epitome of popularity when it is converted into a movie. So the film indirectly helps the novel.
