Steven Spielberg speaks to CNBC's Julia Boorstin on the future of film and technology.

Steven Spielberg and George Lucas, two of the biggest filmmakers of all time, expect some massive upheaval in Hollywood as the division between TV and film content disappears. Spielberg even forecast that the film industry would "implode."

Both see changes in the way movies are made, the way content is distributed and to the business itself, they said during a panel discussion at University of Southern California's School for Cinematic Arts, where they are board members.
