Robert O’Brien’s novel, Z For Zachariah, has become a bit of a young adult classic, but it’s rather dark themes and the fact most of it features just a couple of characters means there’s never been a proper movie version. Now director Craig Zobel is planning to remedy that, and Variety reports he’s brought Chris Pine, Amanda Seyfried and Chiwetel Ejiofor onboard to appear in the movie.

Tobey Maguire, who’ll also produce, has previously signed up to star.

The film is about ‘a teenage girl who lives alone and maintains a farm in the only valley with breathable air in the wake of nuclear war. Her world is turned upside down when two strangers wander in from the forest.’ Interestingly, the book only has one character coming out of the forest, so it seems there’ll be a few changes for the film.

There’s no news on who the actors will play. Maguire is likely to be one of the strangers, John Loomis, while the others will presumably be the other stranger and John’s old co-workers, who he has flashbacks of during an illness.

The film will shoot this summer.
