Metallica singer James Hetfield has lent his voice to a new movie, but he's not singing in it. The rocker narrates a documentary called Addicted to Porn: Chasing the Cardboard Butterfly.
The film examines the impact of pornography on people and societies all over the world. It also looks at the science behind porn and how it affects the brain.
Justin Hunt wrote and directed the movie. He previously did the award-winning documentary Absent, about absent and disengaged fathers. For that film, Hunt interviewed Hetfield.
Addicted to Porn is due out in April on Video on Demand. There will be some screenings before then and you can learn more here.
