Though lacking the reality inherent to the stage, film (unlike stage) offers the freedom to manipulate apparent time and space, and thus to create the illusion of realism – that is temporal linearity and spatial continuity. By the early 1910s, film-making was beginning to fulfill its artistic potential. In Sweden and Denmark, this period would be known as a "Golden Age" of film; in America, this artistic change is attributed to film-makers like David W. Griffith finally breaking the grip of the Edison Trust to make films independent of the manufacturing monopoly. Films worldwide began to noticeably adopt visual and narrative elements which would be found in classical Hollywood cinema. 1913 was a particularly fruitful year for the medium, as pioneering directors from several countries produced masterpieces such as The Mothering Heart (D. W. Griffith), Ingeborg Holm (Victor Sjöström), and L'enfant de Paris (Léonce Perret) that set new standards for film as a form of storytelling. It was also the year when Yevgeni Bauer (the first true film artist, according to Georges Sadoul ) started his short, but prolific, career.
