British film Harry Potter and the Prisoner of Azkaban was second, followed by Spider-Man 2, The Day After Tomorrow and Troy.
Cinema ticket sales increased by 11% at the UK and Ireland box office, with total takings of £576.34m.
The number of recent UK films shown on terrestrial TV increased by 51% but still only made up 4.5% of films shown.
Visits to the cinema increased by 10% between January and August, with more than 117 million people attending.
"Cinema-going remains one of the most popular forms of entertainment in this country," said the UK Film Council's chief executive officer, John Woodward.
The Prisoner of Azkaban is the third Harry Potter film
"British films have put in a strong performance at the UK box office so far this year with two UK films - Harry Potter: The Prisoner of Azkaban and Troy in the top five of the biggest earners at the box office," he said.
The films were mostly shot in the UK, although they were both funded by US company Warner Bros.
Shrek 2, Harry Potter and the Prisoner of Azkaban and Spider-Man 2 were still on release as of 17 October when the figures were compiled, so their gross will have increased since then.
People from London, the Midlands and Lancashire made the most cinema visits between January and the end of August.
Those based in northern Scotland and the Borders made the fewest cinema visits.
