John Lone
Critic Richard Scheib said, "The film was part of a brief revival of the old caveman vs dinosaurs genre, along with "Quest for Fire" and "Clan of the Cave Bear", in which earlier action-fantasy films were redressed with a much stricter regard to anthropological realism. "Iceman", using modern science, became one of the more refreshingly intelligent films. The film is knowingly well-informed on anthropology and biochemistry and never resorts to cheap cliche or hackneyed elements." Harlan Ellison called the film "magnificent", citing excellent acting (particularly on the part of John Lone) and directing that contribute to genuine emotional appeal.
