Robert De Niro and Ben Stiller's latest Meet the Parents sequel was the top film at the UK and Ireland box office over the Christmas period.
Little Fockers made more than £3 million in its first five days on release, knocking the previous week's top film, Tron Legacy, down to three.
Chronicles of Narnia film The Voyage of the Dawn Treader remained at two.
Harry Potter and the Deathly Hallows Part 1 fell one place to four in its sixth week on release.
Little Fockers, which sees De Niro and Stiller play a bickering father and son-in-law, also topped the North American box office chart over the same period.
Despite being coolly received by critics, the film made $30.8m (£20m) between 24 and 26 December in the US and Canada.
Bollywood release Tees Maar Khan came fifth in the UK chart, with 3D animation Megamind in sixth place.
Another family film, Arthur and the Great Adventure, made a disappointing debut in ninth place with takings of less than £85,000.
Lower down the chart, a seasonal re-release of Christmas classic It's a Wonderful Life made more on a screen by screen average than half of the titles in the Top 10.
Despite playing on just 52 screens the Jimmy Stewart favourite made just over £680,000, according to figures collated by Screen International.
