In an effort to more closely mirror the union of Hollywood and Silicon Valley in filmmaking, the American Film Institute has teamed director James Cameron and John Warnock, chairman of computer software giant Adobe Systems Inc., to co-chair its new Advanced Technology Council.A year and a half after the creation of the American Film Institutes’ Apple Computer Center, the council is now attempting to bring the two industries even closer together. Nick DeMartino, director of the AFI-Apple Computer Center, will also head the new council. To kick it off, a series of programs called “Digital Media and the Future of Cinema and Television” will be held in Northern California for software and computer engineers to interact with filmmakers. AFI has lured Trip Hawkins, CEO of 3DO Co., to give a presentation on his new multimedia player in February. Also planned are workshops with computer software designers, Steven Sidley of Sidley/Wright & Associates, Adobe’s Randy Ubillos and Pixar Corp.’s Kai Krause.
