Despite a dud for a title, John Carney‘s Can A Song Save Your Life? sounds intriguing, particularly when you consider that Carney is the man who brought us the incredibly charming Once and that he had lined up a somewhat unexpected pair to top-line his production. Back in February, the project was announced with Scarlett Johansson on board to play a young singer looking to break into the music biz after a bad break-up, alongside Mark Ruffalo as a record producer who turns her life around (professionally and personally) . It was set to be a fun little reunion for the Avengers pair, something more romantic and pleasing to the ears. But now Johansson is out and Ruffalo’s name is nowhere to be seen in the latest dispatch regarding the film. ScreenDaily reports (via Cinema Blend), that Johansson has stepped away from the project for “personal reasons,” and that her role will now be played by Keira Knightley (not an entirely bad swap, really). The news reports that Exclusive Media will financing and producing the film, in addition to selling it at Cannes, and as far as other stars, it only mentions Hailee Steinfeld (who is set to play the producer’s daughter), there’s nothing about Ruffalo. With the ‘Ruff (go with it) making such a big splash in The Avengers, it seems unlikely that an upcoming production wouldn’t be trading on his name any way they can. Is he out, too?

Actors Scarlett Johansson and Mark Ruffalo are already set to tear apart city blocks together as members of The Avengers this summer, so why shouldn’t they be in a love story together as well? Sounds like the logical next step. To that end they’ve both joined Once writer/director John Carney’s next film, Can a Song Save Your Life? Why the ridiculous title? Well, because, like Once, this movie is also about musicians falling in love. This time the story is set in New York City, where Johansson will be playing a plucky young singer trying to start a career in the music business after getting dumped by her stupid boyfriend. While there she meets a charming though mumble-mouthed record producer (Ruffalo) who’s been down on his lucky lately (you know, because he’s a record producer), and the two start up a fling that manages to turn both of their lives around.
