Alright, all you Blu-Ray owners with BD-Live, time to reap the rewards of owning Blu-Ray.
If you have a Blu-Ray player with Internet access and just recently bought The Dark Knight on Blu-Ray, you have the chance to get in on the live chat with director Christopher Nolan. If you haven't already, sign up for Warner Bros BD Live through both your player and your computer. Once you've done that, you should receive an e-mail to RSVP for the live screening.
The live-screening chat is on for December 18th at 6pm (PST) 9pm (EST).
You'll need both your Blu-Ray player and computer connected to Warner Bros. BD Live. Questions can be submitted on the Warner Bros BD Live website and I assume they'll be answered on the Blu-Ray feature.
