Thanks to a blog dedicated to Hayden Christensen we managed to find out that Lucasfilm has been promoting the Saga via China's CCTV-6 channel in a special 30 minute interview with Hayden Christensen and Anthony Daniels (voice of C-3PO). George Lucas, JJ Abrams, Kathleen Kennedy and a couple of others make appearances in that and other videos that can be found in the link below: http://www.m1905.com/video/play/728583.shtml
Besides the fact that it's great to see Hayden again talking about Star Wars, it also brings to mind a couple of other things that are going on inside the mind of Lucasfilm. As China has become an increasingly more important country in terms of box office results, this special was probably a move by Lucasfilm in order to bring the Chinese up to the hype of Episode VII and get those who haven't seen the films interested about it. And what better way to introduce Star Wars than to bring the main character into this special?
Despite the fact that Hayden said his appearance in the upcoming film was "unlikely" let's remember also that JJ Abrams denied his involvement in Episode VII only to later appear as director 2 months later...so how knows?
So even if Hayden doesn't make an appearance in Episode VII, it's good to see that Lucasfilm hasn't forgotten of seeing the importance of the saga as a whole, despite what some may be led to believe. And who's to say that we won't see Hayden again as Anakin in the future?
