CITY OF GOD director and screenwriter reteam for Aristotle Onassis biopic

Fernando Meirelles is reteaming with screenwriter Braulio Mantovani on a new project about the life of the Greek shipping tycoon Aristotle Onassis. Meirelles was nominated for an Oscar for directing and Mantovani for adapting the screenplay for City of God, one of my favorite films.
According to Vulture, the screenplay is being adapted from Peter Evans’ novel Nemesis: The True Story of Aristotle Onassis, Jackie O, and the Love Triangle That Brought Down the Kennedys. Here is the book's synopsis from Amazon:
Peter Evans’s biography of Aristotle Onassis, Ari, met with great acclaim when it was published in 1986. Ari provided the world with an unprecedented glimpse of the Greek shipping magnate’s orbit of dizzying wealth, twisted intrigues, and questionable mores. Not long after the book appeared, however, Onassis’s daughter Christina and his longtime business partner Yannis Georgakis hinted to Evans that he had missed the “real story” — one that proved Onassis’s intrigues had deadly results. “I must begin,” Georgakis said, “with the premise that, for Onassis, Bobby Kennedy was unfinished business from way back…”
Meirelles also is working on a romantic drama titled, 360. That film is scripted by Peter Morgan and stars Anthony Hopkins, Rachel Weisz, and Jude Law. He's also signed on to direct one of the ten short film segments in the upcoming collection Rio, I Love You.
If you have not seen City of God you really are missing out. It is one of the grittiest drug related dramas aside from Scarface. The Kennedy's have always been intriguing to me, so this sounds like a cool project. What are your thougths on this news?
