Phaedra(s), the acclaimed Polish director Krzysztof Warlikowski’s unflinching postmodern take on the Greek myth, is among the early offerings of the Brooklyn Academy of Music’s four-month Next Wave Festival. The fearless Isabelle Huppert plays the title character, whose passionate desire for her stepson inevitably spells tragedy. A theatrical triptych, the piece combines original text by the Lebanese-Canadian playwright Wajdi Mouawad with excerpts from both Phaedra’s Love (1996), an earlier stage adaptation by the late British playwright Sarah Kane, and the novel Elizabeth Costello (2003), by the Nobel Prize-winning South African author J.M. Coetzee. In French with English titles.
