After WikiLeaks published all the leaked Sony emails to its website, a lot of unknown information surrounding the studio have been made public. However, no one expected Julian Fellowes, creator and writer of the hit "Downton Abbey," to be on the line among those mentioned in the various emails.

Fellowes is mentioned in one of the leaked emails and not in a positive light, according to the New Zealand Herald. Brian Siberell, a leading name in the Creative Artists Agency, criticized Fellowes in an email sent to Sony Pictures CEO Amy Pascal. He also criticized other well-known entertainment names.

"Of the writers whom you named there is the awful Julian Fellowes. Christopher Hampton I like of course, though his recent show with Lloyd Webber stumbled," Siberell wrote in an April 10, 2014 email.

To make matters worse, Fellowes was represented by CAA in the 1990s; however, Siberell's opinion of Fellowes may have been behind the latter's lack of success with the agency.

"It's quite disappointing but on the other hand, I left CAA because nothing was happening for me and now I understand why." Fellowes said. "Having an agent is like any other key relationship in your life. If it works well it's the absolute magic carpet but you have to be aware of the fact that there is an element of luck. Sometimes it just doesn't click."

"I don't think I am a bad writer. I don't think Brian is a bad agent. We didn't click, so I moved on to Independent Talent where I have been very fortunate," he continued.

Many others were criticized and mentioned in the avalanche of emails released through the Sony hack.

In a more positive note, Fellowes will be talking about "Downton Abbey" at Chalke Valley Festival, reports the Daily Mail. The TV drama's creator will lead a presentation titled: The World of Downton Abbey: From the Great War to the Roaring Twenties."

He will appear along with ITN's political commentator Tom Bradby to talk about social changes during the time period the show is set in.
