Agent to testify on Rebel's lost earnings

A Hollywood agent says Australian actor Rebel Wilson could have earned $6 million a film but missed out because of a series of defamatory articles.

Wilson won the fight to allow agent and producer Peter Principato to give evidence as she applied for special damages in the Victorian Supreme Court in her bid to recoup millions in lost earnings after winning her defamation action against Bauer Media.

Principato believes Wilson would have received $5 million to $6 million following on from the success of her film Pitch Perfect 2 if not for the articles.

Wilson's lawyers maintain she's owed millions because she lost roles in the movies Kung Fu Panda 3 and Trolls after articles were published.

However, Bauer barrister Georgina Schoff QC argued Principato's evidence on Wilson's claimed losses as a result of the articles was mere speculation and should be deemed inadmissible.

"There might be any number of reasons Ms Wilson was not chosen," she said.

Justice John Dixon refused the defence application to exclude Principato's evidence.

Principato is expected to give evidence via video link when the hearing resumes on Wednesday.
