Spirited Away is my favorite ^^ But I also reeeally like Howl's Moving Castle and Mononoke Hime :)

My favorite is Kiki's Delivery service! I like the other ones that  have seen but i grew up watching Kiki's delivery service. It's my favorite.

I have such difficulty picking an absolute favourite 
But for one thing I am certain; of all the Studio Ghibli films the ones I like the most are those directed by Miyazaki. I mean, I do absolutely love the film Whisper of the Heart and some of the others are absolutely fabulous, but you just can't beat some of Miyazaki's masterpieces *___*

I can never get into anime but I do love ghibli movies !

My fav is Kiki's delivery service.  Ioved it when I was little.

I love Studio Ghibli movies, my favourites are Totoro and Spirited Away

HOWL'S MOVING CASTLE IS MY ALL TIME FAVOURITE IF HOWL WAS A REAL MAN ID HAVE HIM NOT ONLY THAT BUT MY GRAN CALLS ME SOPHIE. oops caps.

Mononoke-hime, Sen to Chihiro no kamikakushi and Hauru no ugoku shiro shares first place.
