Meryl Streep is learning to play the guitar for her upcoming role in Ricki & The Flash.

The Oscar-winning actress will play a rock 'n' roll mum in the movie and screenwriter Diablo Cody told The Hollywood Reporter: "The reason we haven't shot the movie yet is Meryl's learning to play. Watching her come along has been really inspiring."

Cody added: "Everything you hear, the band has to play and Meryl has to play."
