The 50-year-old comedian – whose real name is Michael Pennington – is considering retiring his act as he worries about his jokes being “taken out of context”.
He said: “I am nervous now about being taken out of context. What do you do if something is taken in the wrong way? Is that a career ender when you are being ironic? It is a massive thing and it is on the horizon and I have to deal with it. In a good way it is going to make me sit down and think about stand-up and think about where Johnny is and where I am and what I want to do with comedy.
“I won’t lie, acting is a real comfort zone as it is written. You can turn up and mess about on the day but it is nothing like the pressure of being Johnny again. So I don’t think I am brave enough to do it without it. But I know when I turn up at gigs I have always gone, ‘Oh no I am going to fail,’ and Johnny goes out and comes out with something I could never come up with.”
Johnny knows it will be a “struggle” for people to see him as Michael rather than his alter ego.
Speaking on Richard Herring’s podcast, he added: “It is going to be a struggle but what I want to do is come out as Michael. When I am directing I am confident as Michael. I want to be confident either as Michael or Johnny. I want to say, ‘This is me now. I have moved on a bit. I have changed a bit.’”
