Brian Cox has revealed playing Succession character Logan Roy means he can't stop swearing in real life.
The actor said he has got so used to spouting foul-mouthed insults as the media mogul that he now blurts them out when not filming.
Cox told how he rarely used bad language in general conversation until he landed the role of Roy, who is famed for his "f*** off" catchphrase.
Earlier this week, Loose Women panellist Jane Moore was forced to apologise after Cox swore during a live interview on the ITV daytime show.
The Dundee-born star was discussing his own similarities to Roy when he let slip a curse.
He said: "The one thing we share in common is a disappointment with the human experiment.
"We do believe that, the current crisis we're living in, I can't believe that we're still in the same – excuse me – s*** that we've been in time and time again."
Cox also swore during an appearance on This Morning last year while promoting his autobiography, leading host Philip Schofield to apologise.
Now in an interview with The Washington Post, the 75-year-old said Roy was to blame for his frequent swearing.
He said: "I think with Logan and I that, of course, there are similarities.
"One thing that Logan's had, one effect he's had on me is one of language.
"I swear a lot more now than I ever have before in my life. I mean, I swear a lot.
"Logan is so free with his swearing, and I used to swear but not like Logan Roy.
"But now he's affected me in that way.
"There's also something liberating about swearing, you know, and I think he uses that as a tool, a liberating tool.
"So there's that aspect."
Cox is cashing in on Roy's swearing by charging fans to tell them to "f*** off" in the style of the character on celebrity message service Cameo.
The actor has been inundated with requests for personalised messages since joining the website last year and recently more than doubled his fee to £517.
Cox won best actor in a TV drama for his role as Roy in Succession at the Golden Globe awards in 2020.
