According to author Jonathan Safran Foer, Portman approached him last summer (11) about adapting his novel Eating Animals for a film project.
In a recent interview with French website Chap, he says, "She contacted me, she told me that she loved the book. I know her now. I will help her eventually but it will be her vision. SheÃ¢â‚¬â„¢s only at the very beginning."
The actress previously credited the book with helping her to maintain a healthy lifestyle back in 2009.
