Nice list of sites, GaylordWilshire! And I see that at some of the blogs in your list there are links to even more blogs about Los Angeles. I'm going to enjoy scanning through the lot of them.
This afternoon I was lucky enough to have located a DVD of
Merton of the Movies, and I borrowed it just long enough to make frame grabs of the scene (actually one single shot) that gsjansen mentioned. It appears to be the only location shoot in the entire film.

I wonder if anyone has ever attempted to compile a list of all the movies Hollywood has made about the movie business?
