FilmFour's Lucky Break failed to come back from a disappointing start last weekend, falling 35% in its second weekend as Columbia TriStar's A Knight's Tale charged into the UK box-office.

Knight's Tale, starring latest Aussie export Heath Ledger alongside local talent including Rufus Sewell, The Full Monty's Mark Addy and Gangster No. 1's Paul Bettany, grossed $2.4m (£1.7m), including previews of $478,775. The period action comedy set in the world of jousting tournaments and scored to contemporary music including Queen and David Bowie screened at 377 sites with a resounding $6,461 site average.

Unshakeable US blockbusters filled much of the rest of the chart, with the top ten filled out by Planet Of The Apes (2), Cats & Dogs (3), Rush Hour 2 (5), Shrek (6), Jurassic Park III (7) and Dr Dolittle 2 (10).

Lucky Break took $330,964 (£229,034), and ninth position, with a site average of just $1,308 from 253 venues. The comedy from The Full Monty director Peter Cattaneo now has a total gross of $1.3m after 10 days on release. With the exception of 20th Century Fox's Josie And The Pussycats, Lucky Break suffered the worst follow-up weekend of last week's seven openers, no doubt hurt by negative press reports about its opening.

In their second weekends, Heartbreakers fell 23% and took fourth place in the chart, while Artificial Eye's At The Height Of Summer dropped just 5%. Pathe's Thai film Tears Of The Black Tiger rose 3% on its opening figures and Optimum Releasing's Le Secret fell slightly by 12%.

Crocodile Dundee In Los Angeles dropped off 24%, taking $388,803 (£267,885) from 219 sites. The UIP title came in just above Lucky Break for the second week running.

The biggest screen average of the week went to Eros International's latest Bollywood release, Lajja, directed by Rajkumar Santoshi. The film managed $167,866 (£115,660) from only 16 sites for a massive average of $10,492.

Just behind Lajja, at 15 in the chart, was Gurinder Chadha's What's Cooking', distributed by Helkon SK. The Thanksgiving-set comedy drama, which stars an ensemble cast including Academy Award winner Mercedes Ruehl and ER's Julianna Margulies, took $65,958 (£45,445) from 22 sites.

The only other opener to make the chart was Warner Bros' Angel Eyes. The Jennifer Lopez thriller fared less well taking just $236,064 (£162,648) from its 191 sites, a meager average of $1,236.

Openers that did not make the chart included the re-release of Enigma Of Kasper Hauser at the NFT, where it grossed a strong three-day take of $8,197. Entertainment's drag musical comedy Hedwig And The Angry Inch took $43,549 from 31 sites, with Metro Tartan's Suspicious River managing just $1,350 on a single site.
