Brendan Fraser's turn in The Mummy: Tomb of the Dragon Emperor failed to shake The Dark Knight off the top spot in this week's box office figures.
It was a third week at number one for the Batman movie, whose £4 million-plus takings were far above The Mummy's £2.9 million takings.
In third place was the film version of the Mamma Mia! Musical which took £2.7 million, while animated summer smash Wall-E was fourth on £1.4 million.
There were new entries at numbers five and six thanks to teen dance movie Make It Happen and Bollywood's Singh is King. The X Files, which was at four last week, slumped to tenth place.
It is the Dark Knight which continues to be successful, however, having already passed milestones like the $300 million (£151 million) faster than any film in history.
The Batman Begins sequel stars Christian Bale as the eponymous hero and Heath Ledger as The Joker. His performance is leading many to predict an unprecedented posthumous Oscar win, following his death from a drug overdose earlier this year.
