The Embryo Hunts In Secret , released in July 1966, is the first film made by Japanese director Kōji Wakamatsu independently of any movie studio. It was released just months after he had left Nikkatsu and formed his own company, Wakamatsu Productions. At the time of its release Wakamatsu was quoted as saying "For me, violence, the body and sex are an integral part of life" which would predict the outcome and plot of the film.
