According to U.K. and Irish distributor Entertainment One, this marks the biggest-ever opening for an American film in the U.K., fifth behind the British Harry Potter and James Bond series.
The fourth film in the "Twilight" series also had the best-ever U.K. 2D opening day Friday, surpassing "Harry Potter and the Deathly Hallows: Part 1" by grossing 6.35 million pounds ($9.9 million) to Potter's 5.9 million pounds ($9.2 million).
"Breaking Dawn Part 1" now has the biggest opening for a film in the U.K. in 2011.
The film, which is directed by Bill Condon, stars Robert Pattinson, Taylor Lautner and Kristen Stewart.
