Hayao Miyazaki is a well-known film-maker and director, and has directed many animated films. I'm too LAZY to type out their summary, but....
Here are some of his popular works:
Howl's Moving Castle (based on the book "Howl's Moving Castle" by Diana Wynne Jones)
Princess Mononoke
Spirited Away
Castle in the Sky
The Secret World of Arriety
There are many, many more, but I don't know where to get a complete list.
I AM AN ABSOLUTE LOVER AND FAN OF HAYAO MIYAZAKI-SENSEI'S WORKS.
To all those who haven't watched even one of his films, I tell, you, WATCH IT!
It will make you enjoy a wonderful mixture of adventure, love, friendship, and of course, love.
As a fantasy-maniac, I guarantee you will enjoy his movies. It may look childish, but I know even adults love it.
If you're looking for a movie filled with epic adventure, fantasy and gives a feeling of friendship and love, I recommend Mr. Hayao Miyazaki's works.
Oh, I don't know if this is complete, but here's a list of his films:
