Horrid Henry: The Movie

11-year-old Horrid Henry uses his magnetic yoyo to steal biscuits from Moody Margaret's Secret Club. Before he can eat them, his mother tells him to do his homework. The next morning, Henry searches for his homework, only to find that after he left it on the dining room table, the other members of the household variously spilled milk on it, stepped on it, and squashed it into the couch, leaving it a mess.

He leaves it behind and has his friend Brainy Brian forge a note from his mother saying his cat ate it. His teacher, Miss Battle-Axe, realizes that this note is forged and that Henry did not do it himself, since Brian spelled "homework" correctly, something Henry is incapable of doing. With Henry in detention, his friends join him to practice for a talent contest. Miss Oddbod, the headteacher, and a pair of school inspectors walk in on their rehearsal. She angrily tells them off.

Vic Van Wrinkle, headteacher of the exorbitantly expensive private academy Brick House School, has been bribing the school inspectors to put pressure on Ashton Primary, the school Henry attends, in order to justify closing the school. Van Wrinkle stands to make a fortune from the resulting influx of pupils. Horrid Henry and Moody Margaret's bad behaviour prompts Miss Oddbod to fire Miss Battle-Axe for failing to enforce discipline, and the school inspectors encourage Henry's pranks and even frame him. Miss Lovely ends up getting fired like Miss Battle-Axe for failing to discipline Henry when she gets slimed by him and Margaret after they argue, which was actually because the school inspectors placed the slime in Henry’s bag. After having to fire another teacher because of Henry, Miss Oddbod decides to ban Henry’s band, the Zero Zombies, from entering the Talent Contest.

With Ashton Primary on the brink of closing, Henry's Great Aunt Greta volunteers to pay for Henry to attend an all girls school (since she thinks Henry is a girl) and his 9-year-old younger brother Peter to Brick House. Miss Lovely gets a job at Brick House, where she notices the school inspectors. Peter distracts the staff and pupils by performing numerous arrangements of "Frère Jacques" so that Miss Lovely can spy on Van Wrinkle and the inspectors. She is caught by Van Wrinkle, but covertly passes notes about his plan to Peter.

Meanwhile, Henry's new schoolmates immediately realize he is a boy and begin hunting him. Margaret, who has also been transferred to the school, comes to Henry's aid, and the two escape. The traumatic experience motivates them to work together to save Ashton Primary. Henry decides to win the talent contest with his Zero Zombies band, hoping that this will make them famous enough that they won't shut the school down. They sneak in and do compete despite their ban.

After the band wins the contest, Miss Oddbod informs Henry that fame is irrelevant in this case. Henry is later invited to be a Contestant on a game show known as 2 Cool 4 School, with the intention of using the prize money to bribe the school inspectors to leave Ashton Primary alone. In the final round of the competition, he is confronted with Miss Battle-Axe, who challenges him to spell "homework." Recalling Miss Battle-Axe's early admonitions and using "Oh Henry, you horrid boy" as a mnemonic device, he correctly spells "homework" with two "o"s for the first time.

Meanwhile, Peter and his friends try to rescue Miss Lovely, but are captured by Van Wrinkle. Miss Lovely tricks him into explaining his plan while Peter has her mobile phone on speaker phone while on a call with Miss Oddbod, who is shocked to hear what is going on. She tricks the school inspectors to go and get her more ink, and then calls the police. Van Wrinkle attempts to escape, but falls over due to Peter tying his shoelaces together. Vic Van Wrinkle and the school inspectors are arrested. Henry returns and offers the cash prize to Miss Oddbod, who declines it and explains that the school has already been saved. At Margaret's suggestion, the money is instead used for a large party.

The soundtrack was released on 1 January 2011, New Year's Day, by Universal Music TV.[12]

Horrid Henry: The Movie was theatrically released on 29 July 2011, in the U.K. by Vertigo Films.[13][14] It was later released on DVD and Blu-ray on 28 November, that same year, in the United Kingdom.

The film opened at #5 in the box office in the United Kingdom with £1.3 million, in a Top 10 led by Harry Potter and the Deathly Hallows – Part 2 and Captain America: The First Avenger.[15] It was knocked down the next week to #7, by Super 8 and Mr. Popper's Penguins.[16]

The film received generally negative reviews from critics. Review aggregator website Rotten Tomatoes reports that 9% of 22 reviews for Horrid Henry: The Movie are positive; the average rating is 3.60/10.[17] Common criticisms included the unfunny, juvenile humour,[18][19][20] stuttering plot,[18][20][21] and unimaginative use of stereoscopy.[18][19][20] The bright colour palette was widely praised, but generally said to be wasted, given the overall low quality of the film.[18][19][21]

Leslie Felperin of Variety stated: 'Thinly scripted, even for a kidpic, but luridly colored enough to keep even nap needing tots (or parents) awake, this sophomore effort by Brit helmer Nick Moore (Wild Child) reps something of a waste of its impressive roster of supporting thespian talent, while its use of 3D is likewise less than imaginative.'[18]

Derek Adams offered the film mild praise in Time Out: "Horrid Henry is indelibly flawed and disorderly in tone but not devoid of rambunctious charm".[21] When interviewed on Desert Island Discs by Kirsty Young, Horrid Henry book author Francesca Simon stated: 'I haven't seen it (the film)...I had nothing to do with it.'[22]

In an interview with Novel Entertainment, aired out in January 2020 after the success of Horrid Henry: The Movie being aired on Nicktoons, executive producer Lucinda Whiteley said she was 'absolutely (working on a sequel)! And not just one but two sequels, as the story of how Henry ends up saving the world needs more than just 90 minutes!'[10]
