Film recommendations?

I really love anime films by Studio Ghibli. I especially prefer the pacing and mood of films by Hayao Miyazaki. I want something with adventure but with a laid back ambiance. I'm not looking for maudlin dramas, but more optimistic, quirky ones...with maybe some childlike characters. Now, don't restrict your recommendations to animated films, I don't care about where (any country) or when the film was made. The films I'm looking for just have to fit the mood described above.
