《外部空间》是一部优秀的剧情题材影视作品，由芭芭拉·赫希主演的。 Guy Maddin writes, "Tscherkassky has made two films cannibalizing Sidney J. Furie's 1982 Barbara Hershey horror film THE ENTITY, the story of a woman who is continually assaulted and raped either by real ghosts or by awfully adept repressed traumas… The screen literally explodes with a tumult of Hershey faces, shattering Steve Burum's original cinematography into shards of frightened eyes, trembling hands and violent outbursts of self-defense, presented in multiple exposures too layered to count, too arresting to ignore."
