41.In 1920, barely out of his teens, Alfred Hitchcock went to work for an American film company which had opened a studio in Islington, London. His first job at the studio was writing captions （脚本） for silent movies. Within two years, he was writing scripts（剧本） and working as an assistant director.
For the rest of the 1920s, Hitchcock worked on one film after another in Britain and Germany. Filming was often a rough-and-ready（匆忙做成的） affair and the assistant director was required to step in and plug gaps. A cameraman went missing, Hitchcock became a cameraman. A scene needed rewriting, Hitchcock rewrote it. Someone needed to be in charge of money when the film crew was on location, Hitchcock looked after the money.
At the same time, this being the era of silent movies, Hitchcock was learning the language of cinema: telling a story－not through dialogue, but through visual images（视觉影象）. This led to his success later.
