食人族原名：Cannibal ferox，又名MAKE THEM DIE SLOWLY
身居纽约的人类学家葛瑞拉（Lorraine De Selle 饰）和兄长鲁迪（Danilo Mattei 饰）、好友派特（Zora Kerova 饰）结伴前往亚马逊丛林考察土著的生活习俗。抵达目的地后，他们遇见两个躲避外界追杀的毒贩：麦克（Giovanni Lombardo Radice 饰）和乔（Walter Lucchini 饰）。这两个邪恶的家伙利用当地人帮他们从事毒品生产和交易，稍不顺心便对当地人打骂对待。
Advertisements still claim that the movie is banned in 31 countries, even though several countries have lifted the ban since it was first printed.Giovanni Lombardo Radice used the stage name John Morghen to make audiences think Cannibal Ferox was more of an Americanized movie rather than an "obscure foreign film".
Umberto Lenzi used the same music as he used in his earlier film, Mangiati vivi (1980), in this one.Like Cannibal Holocaust (1980), this movie contains several actual animal killings. Though his character kills an animal in the film, Giovanni Lombardo Radice thoroughly objected to the animal killings and refused to participate in them (a double had to be used). Director Umberto Lenzi tried to convince Radice to do the killings by telling him, "De Niro would do it," to which Radice responded, "De Niro would tell you to fuck off."
The Australian title Woman from Deep River was made to cash in on one of Umberto Lenzi's previous films, Paese del sesso selvaggio, Il (1972), which is also known as Man from Deep River.
