Bafta winning comedian Brendan O'Carroll has claimed if critics could write as well as him they would not be critics.
The Irish stand-up is on location in Dublin filming his debut film, Mrs Brown's Boys D'Movie.
O'Carroll said fans will get a snap-shot of Mrs Brown's life back among the fruit and vegetable traders on Dublin's famous Moore Street.
"It was always implied in the TV series that every time she left the house she was going to the market," said O'Carroll.
"This will get a change for the audience, all 15 million of them in the UK, to see the market, to see Moore Street in its blossom. We're using the real dealers as the stall holders, so they've been absolutely magnificent.
"So it's nice to see her at home."
O'Carroll puts his success down to being the right thing at the right time, giving people some nostalgia during the downturn in the economy.
"People are really, really down and this is a comedy that's not trying to be clever and not trying to be anything except make you laugh," he said on set.
"There's not enough programmes on television that you can sit down for half and hour and laugh. That's what we aim to do.
"We're not trying to give a message, we're not trying to say this is how you raise you're family, certainly now.
"What we're trying to say is every bit of this should try to be funny anyway and it's working.
"We're not pleasing the critics, but then if the critics could write what I write they wouldn't be f**king critics."
O'Carroll said thousands of Dubliners have come out to watch the filming of his debut movie, which is directed by Ben Kellett and produced by Stephen McCrum.
In it Agnes Brown finds her livelihood under threat from a ruthless developer and she and her family embark on a campaign to save her stall, aided by a motley troop of blind trainee Ninjas, an alcoholic solicitor, and a barrister with Tourette Syndrome.
It features all the familiar faces from the popular television show, with cameo roles from former Irish rugby international Shane Byrne and broadcaster Joe Duffy.
Kellett said he was thrilled to have assembled such a brilliant cast and crew for the new chapter in the development of the Mrs Brown's Boys story.
"It's a very exciting prospect indeed," he added.
Mrs Brown's Boys D'Movie is filming for seven weeks and should be released in June 2014.
