I’ve been a huge fan of Glen Keane for as long as I can remember.  As a Disney animator, he worked on classics like “The Rescuers,” “Aladdin,” “Beauty and the Beast,” “Tangled,” and “Pocahontas.” And now, for the first time, he has directed an animated film, the gorgeously designed and heart-warming “Over the Moon.”

You have probably seen Keane as a child. His father, the legendary cartoonist Bil Keane, created the Family Circus comic panel, based on the Keane’s own family and with the distinctive round shape. The comic is still run by Keane’s siblings.

Keane gave a virtual interview to Critics Choice members this week. He told us about having his father work from home, drawing Family Circus, and how much it inspired him. When he was very young, his father told him, “I am a cartoonist, but you are an artist,” which made him feel, he said, as though he had just been knighted with a sword. His father gave him a book to get him started, called Dynamic Anatomy, which got him started on understanding how to draw the human figure. One day, when he was about 8, some kids on the school bus made fun of him for drawing nude figures, the classical images of the discus thrower and The Thinker. He said at first he was uncomfortable being laughed at, but then he thought about how much he liked drawing and he said, “I’m different! I like it!”

“Over the Moon,” inspired by a Chinese legend, is the story about a young girl who builds a rocket ship to the moon so she can meet the moon goddess. Keane said that the stories he most loves to tell are about “characters who believe the impossible is possible.” “Over the Moon’s” Fei Fei was “the ultimate.” She has the science and math skills to think through the engineering challenges and the faith that the moon goddess is really there.

I asked about the most important element of character design. He said, “They exist before you design them. It’s a weird thing, but that has been my experience. Like the Beast. I had hundreds and hundreds of drawings of him, but I would look at them and think, ‘I don’t recognize him.’ I like the buffalo head shape, the lion’s mane, the boar tusks, the cow ears to make him friendlier, and then suddenly — that’s him. I felt like he was looking at me. It’s a revealing of the character. For Fei Fei, I wanted to see that intelligence, that spark, thinking her way through things, but also that faith.” He said he focuses on the hair — making a joke about compensating for his own lack of hair. But it is always a symbol of the struggle of the character. “For Rapunzel, her hair was irrepressible, uncontainable. For Pocahontas, it showed the spirit moving in her. For Ariel, the hair always looked like it was floating in the water. Tarzan was like a wild animal with the dreadlocks. And for Fei Fei, her chopped off hair is a constant reminder of that chaos in her life. That design choice dictated so much, too. hHer eyebrows had to be really bold and strong. And if you’re going to make a mistake in design, don’t let it be in the eyes. They are the windows of the soul.”

Keane told us about his first assignment at Disney, one brief scene in “The Rescuers” of a character named Bernard sweeping the floor. But he couldn’t get it right. “I thought I was single-handedly going to destroy Disney’s reputation. Pencil points were breaking off.”

Keane asked Eric Larson, one of the “Nine Old Men,” the legendary Disney animators of films like “Pinocchio” and “Cinderella,” for advice. “I thought Eric was going to give me some kind of a formula.” Instead of guidance on the movement, Larson asked, “What kind of a guy is Bernard? Does he care about his job? Of course he does! He wants to sweep up every speck off that floor.” “Within seconds he was the character,” Keane told us. “I realized that sincerity was make-believe. That’s been the thread for me in everything I’ve done, to live in the character, to believe in it, the passion of becoming something you can see and feel in your heart.”
