Love is a trivial memory of everyday life
The love between parent and child and love for humanity in the bookshelf scene is often talked about, but I really like the small details that create a sense of realism that you wouldn't notice unless you looked closely. In the scene inside the spaceship, if you look closely you can see footprints on the wing of the craft visible through the window, and I really love that. Other things I like include the gesture of someone removing a pen floating in zero gravity with their hand, and the feeling of dust that has accumulated on each small item. I think it's great that the sense of everyday life that exists in the film is valued and portrayed so well.
When my serialised work "Moriyama Junior High School" was made into a film, I was shown around the set, and there were things in bookshelves that weren't supposed to be open. The art director said, "There's something that's created by placing things there," and I thought that was amazing. It really made me realise that you can create something great by paying attention to even the parts that can't be seen.
When I draw manga, I also find it important to deliberately draw things that don't need to be drawn. I think that the seemingly useless parts contain the latent memories that reside within everyone. A long time ago, a friend complimented me on my depiction of a can of coffee sitting on a windowsill. It's not something that needs to be drawn, but it's true that it would be placed there (laughs). It's those small, everyday memories that I treasure, and I think that's how I depict love. I sense that same love in "Interstellar."
