"It's called Father Figure, and is about a stay-at-home dad," the 40-year-old stand-up comic said. "It was inspired by what happens when my wife Brenda goes out and I'm left with the kids. Basically, it's a complete disaster because they don't do what I tell them, and they listen to absolutely nothing I say."
"So the show is just about all the mad s*** that happens. It's a bit like Scooby Doo meets One Foot In The Grave."
The Ballinteer native will star in the self-penned comedy pilot and can't wait to start shooting next year. "I'm really looking forward to it -- I think it's going to be incredible."
The idea for the show started out on Jason's successful radio show. "It came from my show on Radio 2. I think the BBC is really interested in Irish comedians at the moment, what with the success of Brendan O'Carroll's Mrs Brown's Boys."
Jason is a big fan of sitcoms and says he can hardly believe that he has finally written one.
"I watch them all -- Family Guy, Modern Family, Black Books -- all of them. It's been a big dream of mine to write something like this. I'd never have thought I would get the chance to join the ranks of the television sitcom world."
Jason plays disorganised dad Tom, while former Father Ted actress Pauline McLynn will once again be playing the part of Mrs Doyle. But this time, Mrs Doyle is Tom's meddling mother, and not a tea-obsessed house keeper.
Jason says that they haven't got round to casting the two sons. "I think that will be the hardest thing -- that and finding someone to play my missus."
