The roster of filmmakers who’ve become shareholders and advocates to Sean Parker and Prem Akkaraju is expanding. I’m told that Martin Scorsese, Taylor Hackford, Frank Marshall and even more can be added to a reported list that includes Steven Spielberg, Peter Jackson, JJ Abrams and Imagine’s Ron Howard and Brian Grazer. There is one major theater chain aboard already, AMC, and it would seem momentum is growing for a new set-top box technology that would allow consumers to see movies at home when they open in theaters, at a $50 price point.
