Actor Eryn Jean Norvill will return to the Sydney Theatre Company nine months after testifying at the defamation trial between former co-star Geoffrey Rush and a newspaper publisher.
The adaptation of William Golding's novel Lord of the Flies opens at the Roslyn Packer Theatre on July 23.
Norvill will take on the off-stage role of dramaturg, or script adviser, the STC confirmed in a statement on Thursday.
The upcoming production, which will run to August 24, stars Australian actors Mia Wasikowska and Eliza Scanlen and is directed by Kip Williams.
Rush was awarded $2.9 million in May after winning his Federal Court case against the Daily Telegraph's publisher, Nationwide News, and journalist Jonathon Moran.
It's the highest defamation payout to an individual in Australian history.
Justice Michael Wigney in April found the Telegraph and Moran were reckless regarding the truth when they reported Rush had been accused of inappropriate behaviour during a STC production of King Lear in 2015-16.
They tried to prove a truth defence at trial based largely on the evidence of Norvill who didn't participate in the newspaper articles.
She alleged Rush sexually harassed her during King Lear when she played the daughter of his leading character.
Justice Wigney ultimately said Norvill was at times "prone to exaggeration and embellishment" and he wasn't persuaded she was an entirely credible witness.
But Norvill stood by her testimony, stating: "I told the truth. I know what happened. I was there."
Nationwide News and Moran are appealing Justice Wigney's ruling with the case due back in court on June 12.
