"Zachariah" is a psychological thriller, set after an apocalyptic event, said the Hollywood Reporter.
The post-apocalyptic feature will be directed by Craig Zobel.
The film is based on the life of a teenage girl (Seyfried) who is the sole survivor until a scientist (Ejiofor) finds her farm, and the two fall in love. Arrival of a young survivor (Pine) complicates the matter.
The script of the film is written by Nissar Modi. It is an adaptation of Robert C O' Brien's classic science fiction novel.
