Anthony Daniels said that he won't voice C3PO. However he will ones again step into C3PO costume aswell as being the voice.
"In an Entertainment Weekly interview, Daniels said that director J.J. Abrams initially asked if he'd be up for just voicing C-3PO. That drew an emphatic no from Daniels."
"He knew I’d say that," said Daniels when referring to his negative response about just voicing a CGI Threepio. "There’s no way I would just do the voice. I also said that it can’t be the same suit. I will tell you that the team then got together and built a new suit. They made an entirely new look-a-like with changes that you will never notice [on screen] that made my life a lot easier."
C3PO was only CG in a few scenes in the prequel trilogy, something Daniels did not think very high off.
Also the three spin off Star Wars movies, it is said the third one of them will be about Obi-Wan. Ewan Mcgregor has before said he is very much up for reprising his role as Obi-Wan, if he should get the chance. That will the bring us a spin off series with Boba Fett, Han Solo and Obi-wan.
To begin with i was not very crazy about these news, but since Boba and Obi is in the talks as spin off movies i'm looking forward to them aswell. Ewan Mcgregor was the best thing about the prequel movies and he did an excellent job as Obi-Wan. I hope the movie takes place either in between episode 1-2, a very important time that only the Clone Wars dealt with. There is great potential in Obi-Wans battle between him and his masters killer. There was alot of important things the prequels missed about Obi-wans journey, that only was covered in the Clone Wars Tv show.
or i hope it takes place after episode 3, and deals with Obi-wans time in exile on Tatooine.
