ANGER AFTER DEATH (1971)

A film mingling documentary and dramatic elements to portray the effects of the threat of chemical and biological warfare on the contemporary mentality. The chemist who manufactures the secret weapons, the scientist who comments on them with complete detachment, the soldier of the First World War, killed by poison gas, who returns to life to discover the manner of his dying--all make their claims on the audience in an arresting, provocative way.
