Between the Nebula Awards this weekend, my sister getting married next weekend, and my various deadlines, today needs to be another big writing day. I’m sorry I can’t post more, but in return I’ll leave you with this mind-blowing detail from Christopher Nolan’s “The Dark Knight.” Remember the mask the Joker wears during the bank robbery at the opening of the film? It was based on the mask the Joker wore in the first episode of the television series in 1966. Ah, that Mr. Nolan. Such an eye for detail.
