Glen Hansard and Marketa Irglova won an Oscar for their song "Falling Slowly," from the 2007 film Once. Written and directed by John Carney, Hansard's onetime bandmate, it's a movie about two musicians in Dublin, writing songs about past romances and exploring the love growing between them.
It was art imitating life, and perhaps the other way around: Hansard, who plays a Dublin street busker, spent years on the city's streets in real life, earning his keep with his the same battered guitar he plays in the film.
And he and the Czech-born Irglova, who plays an immigrant songwriter, found themselves falling in love in much the way their characters do.
