Starring Russell Crowe, Ray Winstone, Sir Anthony Hopkins and Emma Watson, Noah tells its familiar two-by-two tale of global flooding on a blockbusting spectacular scale before Smith weighs in over the credits alongside the Kronos Quartet for a sensitive reading of Mercy Is, co-written with career-long collaborator Lenny Kaye.

Catholic Online announced the news under the headline: 'Noah movie features Christian Artist Patti Smith.' "Maybe they had me confused with someone else," Smith tells Classic Rock, "but I wouldn't deny being Christian. I was raised a Christian, I follow the teachings of Christ. So, you know, I have no problem with that title."
