PJ wouldn't have physically done the editing himself, so he should have been able to get a little shut-eye along the way
One would certainly hope so - not just for his sake, but for the sake of the quality of the pilot too.
The editor assembles a cut from the footage, which is then fine-tuned and approved by the director. It's a fairly common practice working on film, particularly with digital editing nowadays.
Well, yes.
But there are exceptions. And I'm not saying PJ Hogan is this way because I honestly know very little about him and was making a joke with my previous post. But some directors are extremely hands on and, I suppose, an editor's worst nightmare because I've read accounts of where they'll practically stand over the editor's shoulder, picking which shot from which take they want to use and "supervising" almost the entire editing process.
One suspects, though, that with editing going on while Hogan was shooting, he mustn't be that sort of a director.
