Dame Judi Dench recorded an answerphone message that was played in the last series of the show, and Celia Imrie is set to make a cameo in the new series when it returns to ITV on June 1.

Sir Ian revealed: “It’s the greatest disappointment in Dame Judi’s career she hasn’t actually appeared in this.

“She was all up for appearing in it, she absolutely wanted to appear in it, and she had been written into it but something happened professionally that meant she couldn’t but she did get to record her message.

“Maggie Smith is fuming. Well, I know Patrick Stewart is desperate to be in it. He’s very jealous of this relationship. And others.”

But despite having worked on stage and screen for years, Sir Ian confessed he does get a little nervous recording the comedy in front of a live studio audience.

He said: “I’ve found it a bit nerve-wracking really, when the audience arrives. I rather wish they weren’t there and I could just get on with it. We have to keep stopping and starting and we do each scene twice at least and I worry about, I shouldn’t be worrying, I should be concentrating on. That’s the only negative about it.”

Vicious returns to ITV on Monday, June 1
