“Avatar” and “Titanic” director James Cameron is the most influential individual in British film, a power 100 list published by the Guardian newspaper showed Friday. A panel of representatives from the film industry selected Cameron as the person who held the most influence over films the British cinema-going public decided to watch. Steven Spielberg, director of movies including “Saving Private Ryan” and “E.T. the Extra-Terrestrial” was second, followed by “Inception” star Leonardo DiCaprio, animation king and studio boss John Lasseter and actor Brad Pitt. In 100th place were the newspaper's readers for their participation in recommending and reacting to movies via social networking sites. The list was published to launch the Guardian's film season, which runs until Oct. 22.
