Award-winning BBC1 comedy Mrs Brown's Boys is one of the most popular sitcoms on TV , so much so it was turned into a movie.
The Brendan O'Carroll show may induce mixed reactions from telly viewers and critics - but there's no doubting that it is a worldwide hit and fiercely defended by its fans.
In the film the indomitable Irish matriarch discovers that a plan is afoot by developers to buy the famous Dublin street market where her family has run a fruit and veg stall for generations.
Assembling a band of eccentric allies, she plans to fight back, only to realise her daughter is not interested in taking over the family business.
After the film it certainly appears Mammy Agnes and her family are here to stay.
