Tokugawa Mitsukuni
His novel "Mito Komon Kaikokuki", a fictional history of the travels of Tokugawa Mitsukuni in disguise around the country was the basis of a movie starring Ryūnosuke Tsukigata and was the first of nearly fifty of his novels to be made into movies. It later metamorphosed into the extremely long-running television series "Mito Kōmon", which remains popular to this day and which is largely responsible for turning the historical Tokugawa Mitsukuni into a folk hero.
