I recommend the movie My Neighbor Totoro. It’s delightful for both young kids and adults. This is a Japanese animated film with English voices dubbed. There are just two scenes, toward the end, where there is a word in Japanese on the screen and an English translation at the bottom of the screen, someone would need to read this out for a young child who can’t read yet.
Note, this is a movie which you should see on a high-quality television if possible. The backgrounds are really beautiful and you can’t appreciate them on a small TV or one with a blurry picture.
