Angelina, 38, is said to be so interested in the role she is considering cancelling a planned sabbatical in order to accept it.
โAngie had planned to take a lot of time off next year but this role is very tempting,โ a source told the UKโs Sun newspaper.
โShe has been gripped like everyone else by all the drama surrounding Nigella these past few months and thinks she is a remarkable woman.
โThe story has got it all and sheโs as intrigued as anyone else by it.โ
The will centre on Nigellaโs role in the fraud case against her former personal assistants Elisabetta and Francesca Grillo.
The routine trial took a sensational turn late last year when Nigellaโs ex-husband Charles Saatchi changed sides, backing the Grillo sisters who claimed Nigella had a serious drug problem.
The allegations forced Nigella to admit she had tried cocaine a few times but was by no means an โaddictโ.
