The latest Harry Potter film has broken five UK box office records, according to Warner Bros.
Harry Potter and the Deathly Hallows: Part 1 now holds the record for the biggest three-day opening and the biggest single day in ticket sales.
It also had the biggest Friday, Saturday and Sunday openings in the UK to date.
The film made £18.3m over the three-day weekend, taking £5.9m on Friday, £6.6m on Saturday and £5.7 on Sunday.
The records were previously held by Quantum of Solace and Harry Potter and the Goblet of Fire respectively.
Quantum of Solace held the biggest three day opening and biggest Friday sales with £15.3m and £4.9m respectively.
Harry Potter and the Goblet of Fire held the previous records for biggest single day and the biggest Saturday with £5.6m and the biggest Sunday with £5.2m.
"These remarkable box office numbers are a testament to the talents of the film-makers, cast and to the vision of JK Rowling, the creator of this magical world," said Josh Berger, president and managing director of Warner Bros Entertainment UK.
The latest Harry Potter movie has also beaten the previous opening record for the franchise in the US and Canada.
Harry Potter and the Deathly Hallows: Part 1 took $125.1m (£77.9m) at the US weekend box office, taking it straight to the top of the chart.
The previous best weekend debut in the series was $102.7m (£64m) for Harry Potter and the Goblet of Fire in 2005.
The latest Potter movie, the first of two final films, has now made $330m (£205.5m) in global ticket sales.
Harry Potter and the Deathly Hallows: Part 1 is the penultimate instalment in the fantasy film franchise.
The books' creator JK Rowling said David Yates' film - the seventh in the series - was her favourite so far.
Dan Fellman, head of domestic distribution for Warner Bros, told the Reuters news agency that Deathly Hallows had been a hit with its core fanbase.
"What sets this apart is that the audience has aged right along with the movie and the cast," he said.
In the US and Canada, last week's top film, Megamind, was pushed down to second with takings of $16.2m (£10m).
Runaway train movie Unstoppable was in third spot, taking $13.1m (£8.15m).
