Peter Mayhew and Daniel Logan are at the New York Comic Con this weekend and IGN scored some pretty interesting scoop. Here's a passage from an online article by Steven Horn where the upcoming live action television series is touched upon briefly.
"As for the forthcoming live action Star Wars television show, both Mayhew and Logan would love to be involved. Logan has a meeting with Rick McCallum next week and seems eager to reprise the role. Mayhew, the sage, simply smiled and said "I think he (Chewbacca) is going to be there. He needs to be there. It's all in the lap of the gods."
*UPDATE: This just in from Daniel's management team.
"As much as both want to be a part of the series, there is no news on either of them being a part of the series at all. Also, they both will be at WonderCon next weekend in San Francisco. If either of them or both meet with Lucasfilm or Rick McCallum, it will be a personal meeting purely just to say hello to friends."
