Brendan O'Carroll has revealed that he is working on a new comedy series about Irish peacekeepers in Lebanon.
The Mrs Brown's Boys creator and star told US entertainment industry website Deadline that the planned show is one of a number of projects he has in the pipeline.
"I'm doing a pilot at the moment of another thing that I'm doing called Lebanese Outpost and there's a couple of projects that I'm working on," he said.
"In order to go back and do a [full] series [of Mrs Brown's Boys], I'd have to drop those."
O'Carroll was speaking to Deadline in the US as part of the Television Critics' Association Winter Tour which sees journalists meet the stars of TV shows and the behind-the-scenes talent.
The latest Christmas specials of Mrs Brown's Boys are set to be streamed exclusively on BritBox in the US from January 28.
O'Carroll recounted: "The whole idea of the Christmas Special was, when I started the contract with BBC I said, 'I'm only doing three series. End of story. Three series of six'.
"So, the first series we did six. Then they said, 'Well the second series we do six and a Christmas Special'. So, I said, 'OK'.
"So, we did six and the Christmas Special. And then the third series they said, 'Six and a Christmas Special'. I said, 'Well look, why don't we do two Christmas Specials? Because we're going to be in the studio anyway. Let's get two of them out'.
"So, we did the Christmas Specials. Now the thing is, you know, our real income comes from touring. In order to keep it in the public conscious, the two Christmas Specials really serve that purpose."
O'Carroll was recently a guest on The Tommy Tiernan Show on RTÉ One, where he said he never thinks he has "made it" because he "never had a goal".
