Once is a 2006 Irish musical film written and directed by John Carney, former bassist for Irish band The Frames. Set in Dublin, this naturalistic drama stars musicians Glen Hansard (singer of, again, popular rock band The Frames) and Markéta Irglová as struggling musicians during an eventful week as they write, rehearse and record songs that reveal their unique love story. Collaborators prior to making the film, Hansard and Irglová composed and performed all of the original songs in the movie.
Hansard and Irglová's song "Falling Slowly" received a 2008 Academy Award for Best Original Song and the soundtrack as a whole also received a Grammy nomination. Steven Spielberg was quoted as saying 'A little movie called Once gave me enough inspiration to last the rest of the year'.
