I think the film makers are playing a bit, giving us a fictional version of Detective Abberline, 42nd. It's an interesting link. Maybe he's hunting what he thinks is a serial killer.
I'm concerned about this movie. First the delay in release, which is never a good sign. Then, the Rick Baker interview, in which he was less then positive. And now this. I submitted the story about the editors being hired. I guess I don't know much about what makes news as I haven't seen it posted. Anyway, I'm hoping they have a lot of footage to play around with, because many movies are made by decisions made in the editorial process.
