Italian novelist Elena Ferrante’s bestselling novel My Brilliant Friend is headed to television as an eight-part series, US cable channel HBO and Italy’s Rai television said.

The novel, about two women’s volatile childhood friendship and set in Naples in the 1950s, will be adapted by Ferrante and filmed in Italian, the two TV companies said in a statement.

No casting was announced for the principal roles of ambitious Elena Greco and her enigmatic friend Lila. Italian Saverio Costanzo will direct and production is expected to start this summer.

My Brilliant Friend is the first of four novels by Ferrante about the lives of the two characters amid the changing face of Italy through five decades.

HBO’s president of programming, Casey Bloys, said the series would explore “the complicated intensity of female friendship”.

The four Neapolitan novels have become bestsellers in the US and much of Europe, fuelling intense speculation about the real identity of the author, who uses Ferrante as a pseudonym.
