A leak of more than 170,000 emails and 20,000 documents from movie studio Sony Pictures was published on Wikileaks in 2015.

The entertainment company suffered a cyber-attack weeks before releasing The Interview, a film that poked fun at North Korea.

The emails revealed that actresses Jennifer Lawrence and Amy Adams received a lower fee than their male co-stars in American Hustle.

There were also messages from producers and executives insulting celebrities such as Angelina Jolie.

Leonardo DiCaprio was called “despicable” for turning down a role in a Sony Pictures film.

Mr Assange said the emails were in the public interest because they showed the inner working of a multinational company and were “at the centre of a geo-political conflict”.
