Norwegian director Bent Hamer's O'Horten - his return to local film-making after his US feature, Factotum (2005), from Charles Bukowski's novel - will unspool in Un Certain Regard at Cannes, as Hamer's fourth official entry in the festival.

The selection coincides with Norway's largest promotional effort on the Côte d'Azur, focusing on Norwegian cinema, filming in Norway and tourism in Norway, staged by Innovation Norway,, the film institute and the film commission.

Scripted by Hamer, and produced by his own BulBul Film, O'Horten follows a newly-retired train driver (Baard Owe) in his new life without printed timetables and stop-overs at well-known stations. Match Factory handles international sales.

Factotum and another two Hamer films about slightly-absurd old-age pensioners, Kitchen Stories (2003) and his feature debut, Eggs (1995), were both launched in the Directors' Fortnight at Cannes.

Hamer, whose films have been sold to more than 40 countries, is only the second Norwegian film-maker to have appeared four times in Cannes, after legendary Arne Skouen. He will attend with Owe, DoP John Christian Rosenlund and composer John Erik Kaada.

The Norwegian promotional push will include setting up a sami lovvo - a Lappish tent - on the Croisette, inspired by Norwegian Oscar-nominated director Nils Gaup's The Kautokeino Rebellion, screening in the market.

Apart from Lapps carrying sheath knives in national costumes, other tent inhabitants include Nina Refseth, CEO of the new Norwegian Film Institute which has now merged with the Norwegian Film Fund, the film commission and the Norwegian Film Development.
