Christopher Eccleston has talked (briefly) about leaving the show on the Radio 4 show Loose Ends. We all believed it was due to some unspecified dispute so this tells us little more. He did refuse the anniversary show so clearly it was a big deal. At least he is professional enough to refuse to be drawn on the subject. Who knows? We may yet get him to audio! [Update: yes this is an April story, suddenly doing the rounds]
There is a piece on the Radio Times site covering this: Christopher Eccleston on leaving Doctor Who: “I’m always there in spirit”. My take-away is he does care about Doctor Who; we should also note he has a habit of not overstaying his welcome on many programmes.
