The prize-giving at Cannes is underway, and the Belgium-Canada- France co-production Hors les murs (Beyond the Walls), by Belgian writer/director David Lambert, has taken the Grand Rail d’Or audience award for best feature film during the International Critics’ Week.

The debut feature for the screenwriter-turned-director portrays a young pianist in Brussels meeting a double-bass player from Albania and embarking on a heart-breaking gay relationship.

The Grand Rail d’Or is an audience award given out by a group of French railway buffs who are members of the Ceux du Rail association, and who annually give out trophies in Cannes to their favorite feature and short film.

Hors les murs stars Matila Malliarakis, Guillaume Gouix and David Salles.

The film was produced by Canada’s Boreal Films, and Belgium’s Frakas Productions and Les Productions Balthazar in France.
