Remember the poignant 2006 Oscar nominated musical Once set in Ireland about a couple who write, rehearse and record songs while telling their love story. The director John Carney is at it again tackling love with the help of music, alas the trailer looks pretty generic.
Keira Knightley being the main lead is also a dampener but we are still intrigued mainly due to the presence of Mark Ruffalo and a host of singers/artists/musicians who are part of the story which guarantees the music will be top notch.
