This paper explores critical challenges set by younger artists against heroic action paintings of Jackson Pollock and Willem de Kooning, and contemplates their art-historical and art-educational implications. American action painters as championed by Harold Rosenberg epitomized the postwar avant-garde who was believed to discover the existential being through spontaneous act and gesture, and functioned as the ‘American action hero' who disseminated the ideology of American liberal democracy and dominated the hegemony of the art world during the Cold War period. However, action painting has been challenged since the early 1950s, and became the object of attack and deconstruction by postmodern artists and theorists after the 1980s. Situating paintings by Helen Frankenthaler, Robert Rauschenberg, Art & Language, and Cecily Brown within the historical, political, and gender framework, this paper analyzes the formal, conceptual, and performative components of their work that rendered critical challenges against American action hero. I further suggest the younger generation's pictorial challenges as ‘critical learning' rather than total rejection, and shed light on their use of ‘artistic strategies' as discussed in art-educational pedagogy.
