i do recall interviews with him on the mirrormask dvd and he was relating a story to how he ended up involved with princess mononoke he said something to the effect they went to quentin tarantino for translation and he said no you want gaiman he pronounced his own name to something to the effect of gay man i guess he would be the best source for the pronunciation of his own name but i could be wrong i'm not sure the exact pronunciation of my own last name nor even where it's from
