I've seen and love them both. I'm not sure I could pick my favorite though. I just watched Howl's Moving Castle again at a small anime gathering at a friend's house. I love when Howl is throwing his tantrum because Sofie rearranged his bathroom potions and his hair was ruined. LOL :pinkclap: Talk about your metrosexual scene of the year!

Both the films are really good in my opinion^^
I love Miyazaki's other films too, they're all really interesting and well-drawn.
I think I like Spirited away more than Howl's moving castle, but I don't know why. It just feels like it. Though I like howl's moving castle too :D

2 amazing Studio Ghibli productions , i love both movies a lot.

Howl's moving castle is my personal favourite though , what an extraordinaiy piece of art that is! _o_

You should also watch Princess Mononoke:)

OMG I LOVE Howls Moving Castle. My next cosplay is Sophie.

I've only seen Spirited Away. They have the DVD at the library, and I've got to say that it was one of the best movies ever.

If I looked like any of the characters, I would cosplay as them. (I can't use wigs. They don't work for me.)

I love Spirited away but I've never seen Howl's moving castle.

I've seen both. They're really good. But all his movies kicks ass.

I've read the book that howls moving castle is taken from. It's really good. You should check it out.

Howl's Moving Castle was a great movie! I loves it!

I don't know what to say there both my favorites i remember when i first watched spirited away when it was over i re-watched over and over again Howls moving castle is amazing to i watched it on cartoon network i loved it now i wanna buy it. Miyusaki is an amazing artist all his movies are the best.
