Just watched BEGIN AGAIN, the first film is 7 years from the director of one of my favourites, ONCE...
Rather enjoyed it... it's practically the same story as ONCE but set in New York and with star names in it. It's about a girl songwriter, dumped by her rock star boyfriend and playing acoustic songs in dingy NY nightclubs, who meets with a formerly famous music producer and they decide to make an album, recording live in NY locations... quite funny and with likeable characters and some decent tunes (not as good as the ones in ONCE, sadly...) Minus points for casting the guy from Maroon 5 in a major role and having him screeching over some of the tracks, but I think it's one I'd recommend...
