I forget who said what, but I think the issue was that when folks are talking in this movie, you can't easily tell whether they are saying "2-categories" or "two categories", i.e. a couple of categories. This problem comes up a lot in my life, and I am glad to see it finally showing up in a major motion picture! E.g., I must be careful never to say "functor between two categories", replacing it by "functor from one category to another". I would be shocked if they were talking about 2-categories in this movie. Even mentioning categories must seriously diminish their ticket sales, much less 2-categories. On a wholly different note, how are the category theorists in Sydney? *mbx* 42cf5a6900000000
