Coldplay frontman Chris Martin has discussed writing a song for Angelina Jolie’s new movie ‘Unbroken’, joking that the actress kidnapped him in order to ensure his involvement in the project.

‘Unbroken’ was directed and produced by Jolie, telling the story of World War II hero Louis Zamperini. Coldplay contributed the track ‘Miracles’ for the film, making them one of the contenders for Best Original Song at the 2015 Oscars.

Now, Martin has spoken to Vulture about how it allegedly all came about, stating: “”I got a message [from Jolie] that said, ‘Meet in this undisclosed location. You’ll be blindfolded and picked up by seven ex-Navy SEALs’.”

Martin added: “So they kidnapped me, hit me over the head, and sprayed me with Mace. When I woke up, I was in an office, and Brad Pitt was doing push-ups as Angelina Jolie was just sitting there with her crown on. There was also a guy holding a knife to my throat, and she said, ‘Write me a song, or else’. And Brad Pitt said, ‘Yeah. What she said’.”

Meanwhile, Chris Martin also recently revealed that he once asked David Bowie to record vocals for a Coldplay song but was rejected by the singer.

Martin made the revelation at the BBC Music Awards, a ceremony where Bowie was nominated for British Artist Of The Year and Coldplay performed live. He said: “One time i sent him a song to ask him to sing on it. He called me and said, ‘It’s not one of your best.’ He’s got very high standards and I appreciate that. It inspires the rest of us to keep our standards high.”

Coldplay released their latest album ‘Ghost Stories’ in May.
