In an interview with Men's Fitness where the actor, Adewale Akinnuoye-Agbaje explained how his character's trademark knit hat stayed on his head, turns out, there wasn't much of a secret to be revealed. He stated: "I just put it on my head and it stays there, he says. People think it's Velcro or whatever. All it is is my bald head. You just stick it on the corner. I could do a backflip and that baby wouldn't move."
