"We had four minutes and it was unbelievable."
Bradley Cooper has spoken of his love for Glastonbury Festival, after he spent four days there filming A Star Is Born.
The Oscar nominee, 43, surprised Glastonbury crowds in 2017 as he performed on the festival’s Pyramid Stage.
He took to the stage moments before an appearance from country legend Kris Kristofferson.
“Kris happened to be playing so I asked him if I could take up some of his set,” Cooper said of his Glastonbury appearance.
“We had four minutes and it was unbelievable.”
Describing the Glastonbury experience, he told press at the Toronto Film Festival: “I spent four days there in all and learned so much about its inner workings.
“It’s the largest privately-owned music festival in the world and it is the place that makes and rejuvenates careers.”
He added: “You watch major, huge musicians still get nervous about playing on the Pyramid Stage.
“It’s still this place of fear and beauty.”
A Star Is Born sees Cooper star alongside Lady Gaga in the story of two singer-songwriters who fall in love with each other, while their careers head in two entirely different trajectories.
It debuted to huge critical acclaim at the Venice Film Festival last month, receiving an eight-minute standing ovation.
