The executive co-chairman of Fox spoke at length about the $52.4bn deal(£39bn) – seen as the biggest shake-up in Hollywood since the 1930s.
He told Ian King it was the right move at the right time though he was particularly sad to sell Sky – the owner of Sky News – assuming the takeover by Fox, which is continuing, is eventually given the go ahead.
The deal confirmed on Thursday will bring together the 20th Century Fox film studio behind hits such as Avatar, X-Men and Ice Age together with Disney’s film assets, which include Pixar, Marvel and the Star Wars maker LucasFilm.
The pair are respectively the fourth and second biggest movie studios in Hollywood and the deal means the ‘big six’ that have dominated Tinseltown for nearly a century will become a big five instead.
When asked how harmful allegations about sexual harassment at Fox News had been for the business, Mr Murdoch dismissed them as “nonsense”.
He said: ‘It’s all nonsense. There was a problem with our chief executive,over the year, isolated incidents.
“As soon as we investigated he was out of the place in hours – well three or four days. And there has been nothing else since then.
“That was largely political because we are conservative. The liberals are going down the drain. NBC is in deep trouble.
“‘There are really bad cases and people should be moved aside. There are other things – which probably amount to a bit of flirting.”
The 86-year-old added that he did not believe those allegations had affected investor sentiment towards his businesses.
Included in the Disney sale are Fox’s prized US cable networks, including FX and the National Geographic Channel, as well as international pay television assets including Star TV in India.
Fox has been trying to buy full control of Sky for the last year and the proposed £18.5bn takeover, which was launched just over a year ago, is currently being scrutinised by the Competition and Markets Authority.
Fox said it expected that deal to be completed by the end of June next year.
Disney would then eventually own the whole of Sky.
Other assets included in the deal are Fox’s 30% stake in Hulu, the US streaming service, in which Disney is also a shareholder.
The deal is expected to take a year to complete and will be subject to approval by competition regulators both in the United States and in the EU.
The latter is seen as less likely to have a problem with the takeover but the US, where the US Justice Department has been seeking to block the $85.4bn takeover of Time Warner by the telecoms giant AT&T, may be more difficult.
The combined business will make films that account for two in every five cinema tickets sold in the US – which may raise some concerns among regulators.
Under the terms of the deal, Disney will also take on some $13.7bn worth of debt from 21st Century Fox, making the total deal worth $66.1bn.
Announcing the deal, Bob Iger, the chairman and chief executive of Disney, said: “The acquisition of this stellar collection of businesses from 21st Century Fox reflects the increasing consumer demand for a rich diversity of entertainment experiences that are more compelling, accessible and convenient than ever before.
“We’re honoured and grateful Rupert Murdoch has entrusted us with the future of businesses he spent a lifetime building and we’re excited about this extraordinary opportunity to significantly increase our portfolio of well-loved franchises and branded content to greatly enhance our growing direct-to-consumer offerings.
“The deal will also substantially expand our international reach, allowing us to offer world-class storytelling and innovative platform distribution platforms to more consumers in key markets around the world.”
Mr Iger, who was due to step down as Disney boss in July 2019, will now continue in the role until the end of 2021.
Mr Murdoch described how the deal evolved following a discussion over a few glasses of wine with Mr Iger, who he described as a friend.
“He rang me back a couple of weeks later and said ‘look let’s (have) this conversation a bit more’.”
Under the terms of the transaction, which will be entirely in shares, investors in Fox will receive 0.2745 shares in Disney for each 21st Century Fox share they currently own.
