Christopher Eccleston will play the McGoohan role in the new Prisoner series. He was brilliant as the Doctor. HD, if you weren't already looking forward to this, I think the Eccleston casting means it's safe to start now.
As far as the Doctor goes, Tennant has not dropped the ball. I've seen the first two episodes and a large chunk of "School Reunion" (which featured the return of Sarah Jane Smith and K-9 [about to get his own animated series, btw] as well as Anthony Stewart Head in a decidedly un-Gilesish role) and I think the series is actually getting better!
