Right now I'm reading this book - What Made Pistachio Nuts? by Henry Jenkins. It's about vaudville aesthetic and the shift to narrative in early comedy-musical Hollywood film (1930s or so). Sorry, that sounded like I can't speak or write English.
Anyway, it's by Henry Jenkins and it's interesting. I was reading it on the tram Tuesday and did get momentarily distracted by the elephants (you can see them from the tram as you pass the zoo). And frankly, who wouldn't be? I hope I never cease to be distracted by real live elephants.
I'll report back when I've read more.
