Wuthering Heights is a big responsibility, says Andrea Arnold
Last month, it was announced that Ms Arnold would direct Olivia Hetreed's adaptation of the Emily Bronte novel.
It is the first time that Ms Arnold has taken the helm on a film which she did not write.
Speaking to the BBC, the Fish Tank director said: "It dropped out of the sky before Christmas for me, and I never thought I would ever take on an adaptation of a book of any kind or even someone else's script."
She also revealed that Wuthering Heights is close to her heart, adding: "I think it's close to a lot of people's hearts which makes it a huge responsibility. It may not be to everyone's taste but that's okay."
Wuthering Heights is a "big class story", she stated, noting that all of her films have been about class.
Ms Arnold, who was one of the presenters of TV series A Beetle Called Derek, won an Oscar for her short film Wasp in 2005. She is nominated for a Bafta Award for best British film this year for Fish Tank.
