Scarlett Johansson will sing again — this time, in a movie. Once director John Carney confirmed to the Sunday Business Post Online that he’s cast the actress in his next movie, Can a Song Save Your Life?, which will be produced by Judd Apatow. She’ll play a fledgling singer-songwriter who falls for a washed-up A&R man — Mark Ruffalo and Jim Carrey have been rumored for that role — and Carney promises that Johansson will sing a number of songs in the film. Also, she is so pretty, says the director: “I went out to Los Angeles to meet Scarlett a couple of months ago. She was everything you could imagine — very hot, elegant and she’s really smart.†[Sunday Post]
