Presumably Moffat had input to most of the series 5-7 scripts anyway, I'm not sure the fact he's now credited makes a difference.”
That's why I find it strange. Like RTD, he's almost certainly had input into all the scripts before now. Why is he suddenly taking co-writer credits when he hasn't in the past?
One explicitly mentioned past example I can think of is 'The Lodger'. I remember an interview (or perhaps it was a commentary) with Gareth Roberts where he mentioned that the twist of the top floor of the house being a TARDIS-like craft was Moffat's idea.
I've always strongly believe that 'Amy's Choice' was ghost-written in large parts by Moffat. I've no evidence but it was strongly Moffat in style, was a very important character episode and was written by a writer new to the series who has never been asked back since, which is strange given it was such an acclaimed episode.
Neil Gaiman has also given Moffat a lot of credit for 'The Doctor's Wife', saying 'he made it what it was', which is partly graciousness of course, but he wouldn't say it if Moffat contributed nothing to the script.
This is purely speculation and I'm genuinely asking the question as I don't know the answer: is the onscreen writing credit necessarily the same as the writing credit in the BBC's official documentation? Ie. could co-writers both be paid the fee for an episode but only one be credited onscreen if they both wished it to be the case? I would have to assume they could be. In fact, I remember Neil Gaiman commenting that Steven Moffat was erroneously credited as the writer of the short episode 'Planet of the Rain Gods' on the Season 6 (I think) DVD but he didn't mind as it was a genuine mistake and he was still paid as the author.
I wonder if Moffat is credited as co-writer in terms of receiving writer's fees but was not supposed to have an on-screen credit and the BBC has made a mistake on the announced titles? Again, that is total speculation. We'll see what it says when the episodes are broadcast.
Maybe he really has just had much larger input on three scripts than he ever has previously.
