Believe or not, Elba claims that he “winged” it since he had been just coming off a year where he trained to become a professional kickboxer. Elba explains, “I winged that performance, if I’m honest. Right after I won my professional fight — thank … God — I went to Toronto to work on it. I only had 12 days before I had to go to The Mountain Between Us. When you’re fight-training your brain is completely mush because you’re tired all the time, so I was literally going, ‘This is going to be the end of my career.’”
