Did it take him a while to shake off Mandela?
“Mmm. Yeah. I mean, I didn’t quite shake it off.” It seems he didn’t have the chance. “It was really weird,” he begins. “I’d just done eight months in South Africa. I came to England and the day I came back I had to do reshoots on Thor 2.” He raises an eyebrow. “And in the actual scene my hair was different, my…” He stops and gives an exasperated sigh. “I was like, ‘This is torture, man. I don’t want to do this.’ My agent said: ‘You have to, it’s part of the deal.’ ”
In the scene in question in the superhero movie, “I’m actually falling down from a spaceship, so they had to put me in harness in this green-screen studio. And in between takes I was stuck there, fake hair stuck on to my head with glue, this f------ helmet, while they reset. And I’m thinking: ‘24 hours ago, I was Mandela’. When I walked into the set the extras called me Madiba. I was literally walking in this man’s boots. [Within] six months, the crew, we were all so in love with this film we had made. I was him. I was Mandela, practically,” he insists.
So Mi Mandela seems to be Elba’s attempt to both further honour a hero and icon whom he rightly worships, and to atone for the big-pay-packet commercial work he undertakes. As he says at one point, his approach to choosing films is “two for them, one for you”. For every two movies he makes to increase his profile and/or bank balance, he undertakes one that is more personal, more meaningful. Into the latter category falls Beasts of No Nation
