The Into the Woods star plays a failed musician in the movie and had to cover several songs by artists including Lady Gaga, Bruce Springsteen and Tom Petty live.

Streep also had to take guitar lessons for the project and she was shocked when director Jonathan Demme set her up for sessions with Young.

She says, "When I said I would do the movie, Jonathan Demme was up at the Jacob Burns Center, which is a film centre he runs, and Neil Young was in there recording. So Jonathan said, 'Come by, Neil would like to meet you and maybe I'll get him to give you a guitar lesson, yeah man that will be good'. So my first lesson was 45 minutes with Neil!"
