For some reason, I was under the impression that Patrick Stewart was in the English cast for Howl's Moving Castle, which is the only reason I wanted to see the dubbed version. Turns out he wasn't. A quick check reveals that he's in Chicken Little, coming out later this year, so I must have gotten that mixed up.
I still enjoyed Howl's. Judging by magid's reaction, I guess it's a good thing I didn't remember the book. I'll have to reread that soon.
