"I felt belittled." Eryn Jean Norvill has given evidence at Geoffrey Rush's defamation trial.

Eryn Jean Norvill has told a court it “couldn’t have been an accident” when Geoffrey Rush allegedly touched the side of her breast during a scene where her character was dead on the stage.

The young actor on Tuesday said they were in the midst of a preview performance of King Lear at the Sydney Theatre Company when Rush stroked across the side of her right breast and on to her hip.

She said it hadn’t happened before, with Rush usually touching her face and sometimes her head, shoulder and arm during the scene.

“It couldn’t have been an accident because it was slow and pressured,” she said in the NSW Federal Court on Tuesday.

Norvill was giving evidence at Rush’s defamation trial against Nationwide News – the publisher of the Daily Telegraph – and journalist Jonathon Moran.

The Telegraph last year published articles about an allegation the Oscar winner behaved inappropriately toward a co-star – later revealed to be Norvill – during a production of King Lear in 2015 and 2016.

Rush, 67, denies the claims, including that he deliberately touched Norvill’s breast, and argues the newspaper portrayed him as a pervert and a sexual predator.

Norvill, when asked by defence barrister Tom Blackburn SC how she felt when Rush allegedly touched her breast, said she was probably frightened and confused while “trying to make sense of what Geoffrey’s intentions were”.

“At the time, I was on stage with my eyes closed playing a dead body, so I probably felt very trapped,” she said.

She said she’d already felt shocked, “belittled and embarrassed and, I guess, shamed” during rehearsals for the scene when she heard titters of laughter as she lay on the ground and opened her eyes to see Rush allegedly making groping gestures above her chest.

She told the court he was bulging his eyes, smiling and licking his lips.

Rush continued making sexual gestures towards Norvill during the rehearsal period and would sometimes growl and call her "yummy", she said.

"I just didn't really understand why Geoffrey would make fun of my body or comment about my body if he was my friend and respected me as a colleague," Norvill said.

Novill, who had longer to work with Rush before the production, alleged his lewd gestures and sexual innuendo became normalised in rehearsals but she didn't say anything as "his power was intimidating".

"Everyone else didn't seem to have a problem about it, you know, so I was looking at a room that was complicit, my director didn't seem to have a problem with it, so I felt quashed in terms of my ability to find allies," she said.

Several times while waiting to walk on stage, Rush would allegedly brush his fingers against Novill's and trace them on the palm of her hand.

The actor said once when he stroked her lower back, her "panic levels shot up" and she felt "unsafe and probably sad... because I think Geoffrey's idea of friendship was different to mine".

Cross-examined by Rush's lawyer, Bruce McClintock SC, Norvill denied fabricating parts of her evidence.

She said she "100 per cent" disagreed her claim of sexual harassment by Rush was a "complete lie".

During his evidence last week, Rush denied deliberately touching Norvill's breast, touching her lower back under her shirt when they were backstage and making lewd gestures and comments toward her.

He became emotional when he said that in the scene where Norvill's character had died, he imagined she was his "own real-life daughter and she'd been hit by a bus on the street where we live".

In court last week, Rush was questioned about a lengthy text message he sent Norvill in June 2016. Part of the message read, "Apologies for missing your opening last night (I sent a scrappy hasty message through Mrs Nevin)... but I was thinking of you (as I do more than is socially appropriate...)"

Under cross-examination, Rush also said it was possible he told Norvill she looked "yummy" during rehearsals for the production.

The judge-alone trial before Justice Michael Wigney continues.
