 Sam Raimis "ARMY OF DARKNESS" pays homage to this film. When Ash  has swallowed one of his little dopplegangers, he then grows an eye  on his right shoulder, which results in him splitting into two  beings; Good Ash and Evil Ash. In The Manster, the reporter is  injected with a serum and later develops an eye, which grows into a  head, resulting in him splitting into a good being and an evil one.
