As a space of extremes, the skyscraper has been continually constructed as an urban frontier in American cultural productions. Like its counterpart of the American wilderness, this vertical frontier serves as a privileged site for both subversion and excessive control. Beyond common metaphoric readings, this study models the skyscraper not only as a Foucauldian heterotopia, but also as a complex network of human and nonhuman actors while retracing its development from its initial assemblage during the 19
th
century to its steady evolution into a smart structure from the mid-20
century onward. It takes a close look at US-American literary and filmic fictions and the ways in which they sought to make sense of this extraordinary structure throughout the 20
and early 21
st
centuries. More traditional poststructuralist spatial theories are connected with concepts and methods of Actor-Network Theory in a compelling account of the skyscraper’s evolution as reflected in fictional media from early 20
-century short stories via a range of action, disaster and horror films to selected city novels of the 1990s and 2000s.
