Better viewing experience? Is that the reason you choose high-definition? It seems that Walt Disney thinks the interactivity is what marketeers call the format's unique selling point. Last Monday Bob Chapek, division president at Disney, promised to add many more BD Live elements to its future Blu-ray releases. During the company's first release of a BD Live title Chapek showed his confidence and belief in interactivity.

"The idea of my little girl being able to experience the movie and chat in real time with her grandparents across the country is very exciting to me," Chapek said to The Hollywood Reporter. "We are introducing this important feature on 'Sleeping Beauty,' but imagine the possibilities of extending this to other titles such as 'High School Musical' or, eventually, ABC's hit show 'Lost.' Can you imagine the level of excitement that will create with the tweens or the rabid fan base of 'Lost'?"

Besides a chat-function with grand parents, Disney told that movie makers, and maybe actors will also have live chat sessions. Many don't finish their popcorn before the movie is over, so finishing it while talking to a plain crash surviving actor should make some pretty happy.
