What surprised me about the location shots was how long and flat the main street of Collinsport was.
I didn't notice the magic hat in the coffeeshop, because I was too busy thinking about the hair of the waitress. Was that Susie? Whoever it was, she needs to tie her hair back the way Maggie does, so it won't get in people's food. Incidentally, if Roger wanted to treat Vicky to a nice breakfast, was that the best he could do? Yeah, I suppose it may well have been, despite the length and flatness of Collinsport's principal street. What a lot of trouble Roger went to, to hide the fact that his only reason for having anything to do with Vicky this morning was to get her alibi for him into the sheriff's report to the coroner!
The scene with Burke and Vicky at the front door of Collinwood made me think about lenses, because the distance from the front door to the drawing room door, and then to the windows, seemed quite long. (It was also flat, but that didn't surprise me.) When they do a shot from inside, to the left of the front door, looking up to the landing, it makes that distance seem far and the distance from front doors to living room doors narrow, so I guess they're using the exact same lens then. I don't know anything about these things, but it's sort of fun when shots like that make even me think about them.
