Finally, Idris Elba is leading a campaign to stop knife violence in London. The Golden Globe winner is involved in the initiative promoted by London’s Arsenal Football Club and Adidas. Elba appeared at Sunday’s Emirates FA Cup in London matching Arsenal against Nottingham Forrest.

“It’s absolutely in response to the knife crime crisis that we’ve got going on,” Elba said in an interview at the match. “Last year, 30 kids — I’m gonna say ‘kids’ — died senselessly over knife crime. And the year before that, and the year before that…It’s an ongoing problem. [Sportscaster] Ian [Wright] and I teamed up with Arsenal and Adidas to make a point and say something about it.”
