LONDON (Reuters Life!) - Robert Downey Jr. and Zach Galifianakis topped the British box office in the calm before the storm expected to be unleashed later this month by the latest Harry Potter movie.
Their pregnancy-themed road movie "Due Date" made a modest 2.3 million pounds ($3.72 million), according to Screen International on Tuesday, but it was enough to keep another newcomer "Jackass 3D" in second place with 1.7 million.
"Harry Potter and the Deathly Hallows: Part 1," the first of two big budget pictures to be based on the last of J.K. Rowling's hugely popular books, opens in Britain on November 19.
The three orphan girls of family movie "Despicable Me" slipped a spot to third while last week's chart-topper, blood-spattered "Saw 3D" was down to fourth.
The chilling suburban frights of "Paranormal Activity 2" were down two at five, just above Bruce Willis, Morgan Freeman, John Malkovich and Helen Mirren as former CIA agents on the run in "RED" which fell to six from fourth.
Facebook biopic "The Social Network" was down two at seven.
"Let Me In," the story of a bullied young boy who befriends a female vampire, made its debut at eight while director Mike Leigh's acclaimed study of a middle class suburban couple in "Another Year" came in at nine.
Simon Pegg and Andy Serkis in the story of two 19th century body snatchers "Burke and Hare" were down four at 10.
