I can get easily bored with movies. So much cliché… predictability… canned Hollywood repetition. And – being a musician – I am particularly critical of music-centered stories. That being said… I was delightfully surprised by Once.
I think the movie is one of the best independent flicks I’ve seen. I watched it with my wife – we found it full of passion and sincerity. Particularly, it was refreshing to see professional musicians acting in lead roles with such engaging realism… probably so engaging precisely because they aren’t actors, and therefore their acting was much more believable, if that makes any sense. 
Without giving anything away, the movie is about two amateur musicians each struggling in their own way. They by chance embark on a week-long musical collaboration that culminates with them recording their songs over a weekend. Throughout the movie each of them shares songs that find their way into the storyline (and ultimately onto their recorded CD).
Mere hours passed after watching Once before I bought the soundtrack… which was filled (pleasingly) with all the songs from the movie. For fellow musicians especially, I highly recommend this movie and its soundtrack.
From wikipedia…
Once is an Academy Award winning 2007 Irish musical film written and directed by John Carney. Set in Dublin, this naturalistic drama stars musicians Glen Hansard (of popular Irish rock band The Frames) and Markéta Irglová as struggling musicians. Collaborators prior to making the film, Hansard and/or Irglová composed and performed all but one of the original songs in the movie.Shot for only €130,000 ($160,000), the film was very successful, earning substantial per-screen box office averages in the United States. It received extremely enthusiastic reviews and awards such as the 2008 Independent Spirit Award for best foreign film. Hansard and Irglová’s song “Falling Slowly” received a 2008 Academy Award and a 2008 Grammy nomination, and the soundtrack as a whole also received a Grammy nomination.
