Re: 50th Anniversary Special - Eccleston Reconsidering?
He's on record as praising the Moffat 2-parter he did a bunch of times but uh... that's it as far as his episodes go.
There is also a reasonably well sourced story that at some point during shooting of the Dalek/Father's Day block he remarked to RTD: "Why aren't all the scripts as good as this?" Which was a bit tactless as RTD had written all but one of the scripts he'd done up till then, and didn't help the atmosphere between them.
"Some days are better than others. They say that where I come from."
"Loudly, I imagine, on the day you left."
