Emma Watson says at first she was unsure about tackling Noah, because she thought it would be 'cheesy'.
Watson will be back on the big screen at the beginning of April, as she teams up with director Darren Aronofsky for the first time.
And the actress reveals that it wasn't until Aronofsky laid out his vision for the film, she got on board.
Speaking to the Mail on Sunday, the actress said: "To be honest, the idea of making a film of Noah seemed really cheesy to me - the dove and the rainbow the two-by-two ... Darren is the lord of darkness and grittiness.
"And then he explained it to me as this really interesting post-apocalyptic world - not set in the past, but not set in the future, and not a sandal in sight."
Noah will be played by Oscar winner Russell Crowe, while Jennifer Connelly, Logan Lerman, Anthony Hopkins and Ray Winstone are all on board.
Noah is the first big screen outing for Watson since she made a cameo appearance in comedy This Is The End last year.
She has recently bee linked with The Little Mermaid, a film that could possibly see her reunite with director Sofia Coppola.
Noah is released 4th April.
