Fear transforms into terror when ampliﬁed to an extreme. From Darwin: “Fear, Terror. The word ‘fear’ seems to be derived from what is sudden and dangerous.”1 Extreme fear transforms into paranoia, an emotion reﬂected particularly well in ﬁlms of the sci-ﬁ genre. Post-9/11 sci-ﬁ expresses fear, anxiety, panic, and outright paranoia about humanity’s fate in a violent, chaotic universe. A number of signiﬁcant sci-ﬁ ﬁlms referencing the terrorist attacks surfaced after 9/11. Apocalypse is the form paranoia assumes in the genre. In apocalyptic ﬁlms, paranoia symbolically stems not from fear of terrorists but from fear of outside forces poised to annihilate humanity and the entire earth.
