Mind Game (マインド・ゲーム, Mind Game?) is a Japanese animated feature film based on the comic by Robin Nishi. It was written and directed by Masaaki Yuasa and animated primarily by Studio 4°C. It is unusual among features other than anthology films in utilising a series of disparate visual styles to tell one continuous story. As the director commented in a Japan Times interview, "Instead of telling it serious and straight, I went for a look that was a bit wild and patchy. I think that Japanese animation fans today don't necessarily demand something that's so polished. You can throw different styles at them and they can still usually enjoy it."
