[4] It was written by series creator (and company director of both That's Nice Films and Bocflix) Brendan O'Carroll, who also plays the lead role.
The film sees Agnes Brown go to court to protect her family's stall at Dublin's Moore Street market from a corrupt Russian businessman who wishes to convert it into a shopping centre.
Irwin (Dermot Crowley), a TD (PRIC) who is in an arrangement with a ruthless Russian businessman who wants to put all the market stalls out of business and open a shopping centre on the site.
This leads her to go to confession, where she admits (unknowingly also to a Russian mobster) that she briefly put her children in care when her husband died, but continued to claim the child support money.
Eventually being found by the river by her daughter Cathy (Jennifer Gibney), she admits all in a tearful moment on the Ha'penny Bridge, telling her how she told the nuns that she thought she could look after two of the six children, but when asked to pick she was unable to.
Meanwhile, Agnes' son Dermot (Paddy Houlihan) and his lifelong criminal best friend Buster Brady (Danny O'Carroll) try to get the receipt.
After failing to break into the restricted area of the NRS they recruit a troop of blind trainee ninjas, led by Mr. Wang (also played by Brendan O'Carroll).
After navigating air ducts out of the NRS, Agnes, Buster and Dermot are chased by the mobsters and the Garda, jumping in the River Liffey.
At this point, Cathy stands up and gives a speech on how special Moore Street and its market is, and her intention to run her mother's stall when her time comes, to Agnes' joy.
After their pursuit continues in a Nissan Navara and finally a dash on a stolen horse, Buster and Dermot deliver the receipt to the courtroom just in time to have the case against Agnes dropped.
In September 2012 it was reported that an estimated £3.6 million deal was in place with Universal Studios to start production on the film version of Mrs. Brown's Boys.
He was highly critical of the Chinese character Mr Wang, played by O'Carroll "with his eyes narrowed and Ls and Rs switched, while making little karate-choppy motions in the air with his hands", calling it "something close to anti-funny".
He also said that the sitcom's inclusion of bloopers and characters breaking the fourth wall didn't translate to the format of cinema without "very clever lateral thinking", which the film lacked.
[20] Donald Clarke of The Irish Times called the film "overstretched, underwritten, sluggishly paced and unsettled by the discombobulating move from studio to location" and concluded, "the gags are clunky, the dialogue is leaden and the story is threadbare.
"[21] Another 1-star review came from Empire, who remarked: "almost avant-garde in its commitment to unfunny, it's shambolically performed by the majority of its cast, and shot and edited in a fashion so slapdash it seems like a movie made almost entirely by competition winners.
is not only out of its comfort zone, but full of cold, mean-spirited gags about the blind, an Indian man everyone thinks is Jamaican (um, LOL?)
Though Ward enjoyed the 1970s-inspired politically incorrect humour, he noted that some moments caused him to wince rather than laugh, saying the ninja character "makes Benny Hill's Chinaman seem sensitive and respectful".
The first spin-off film is to be entitled Wash and Blow if it is produced and it will see O'Carroll take on the role of salon owner, Mario, alongside Rory Brown and Dino Doyle.
