The story of a young Albanian woman married to a heroin addict in an effect to get Belgian citizenship, the film is the brothers’ usual blend of low-key realist cinematography and intensely gripping narrative.

The sense of revelation may not be there as it was with Rosetta, however, and the jurors may well be looking for something bigger and more of a statement - and there’s no shortage of films like that in competition this year.

But as a film that’s very much about the new Europe, and the street-level problems that rarely get covered in film, Lorna certainly commands attention.

Two new discoveries in festival sidebars:

One is Chilean film Tony Manero, set in the days of Pinochet’s regime, about a demented middle-aged John Travolta wannabe with a very nasty vicious streak. Featuring possibly the most rebarbative protagonist since Gaspar Noe’s Seul contre tous, Pablo Larrain’s disturbing film also wins points for being the only ever film about the disco era to eschew kitsch entirely. Some good dance routines, though.

Also to watch for: Unwilling, by Ruben Ostlund, a Swedish film told in fragmented style - rather like Michael Haneke’s Code Unknown - about a miscellaneous group of characters and the generally messed-up nature of modern life. Echoes here of Todd Solondz, Neil Labute and perhaps a touch of Festen - but with a cool eye for social embarrassment and not-quite comedy that’s very much Ostlund’s own.

Back in the competition, there’s no clear critical consensus yet for a favourite, but overall thumbs down to Serbis, a shambolic picture of life in a Filipino porn cinema. It didn’t endear itself to critics either by having an ear-grindingly painful loud and abrasive sound design.

But it does deserve some points for best line in a sex scene: “I think my boil just burst.”
