Moffat is a colossal liar, and not a very good one. I am really, really, looking forward to the tell-all stories that come out in, say, ten years time when people look back on his time in charge. Like, a lot of people from the John Nathan Turner era later came out to say he was a bit of a cock at times, exposed a lot of the lies that went into the media etc. I'd love to see what people think of Moffat.
Because it's widely said that the first assistant producers left in a rage because they couldn't work with him. As did the most recent, too. Also, maybe I'm reading too much into it, but Matt Smith didn't look happy at all. He didn't look like a man who has done a job he enjoyed and is leaving satisfied, as Tennant did. He looked to me like a man who had had enough. But that may be me looking for things that aren't there.

The trailer thing is so ridiculously stupid! The whole point of a trailer is to publicise the program. So, you're going to let these thousand people at Comicon see it and nobody else? And of these thousand people, how many were going to watch the episode anyway? Approximately ALL OF THEM. A trailer is supposed to drum up excitement, get people who might not have watched to go, 'Hm, Maybe I'll give that a go!' All he has achieved with this insane secrecy is to annoy virtually everyone in the fandom. Cockend.
