Natalie Portman will no longer be eating cheesecake on Shavuot - because reading Jonathan Safran Foer's novel Eating Animals persuaded her to become a vegan.
The Oscar-winning actress is now planning a documentary, based on the book.
Jonathan Safran Foer told a French website: "Natalie Portman is going to make a movie of it. She wants to make a very personal documentary.
"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. She's only at the very beginning."
