During a recent interview with Level, the actor revealed that he had to go to therapy after filming the movie since he says playing the role of such a hated figure in history affected him physically and mentally. In the film, Stanfield’s character poisons Fred Hampton, and the emotions from that affected the actor long after the cameras stopped rolling, even causing him to suffer from panic attacks. “In the scene where I had to poison him, a lot of it didn’t end up making it to the final cut, but we shot [me mixing it in] Kool-Aid, and I had to go through all those emotions,” he said. “With somebody like Daniel, who I just respect as a human and an artist, as Fred Hampton, it felt like I was actually poisoning Chairman Fred Hampton.”

“So sometimes your body thinks that’s real, everything you’re putting it through. It’s no wonder I’ve been feeling so stressed out and having panic attacks. I realized going forward before I step into something like that again, maybe have a therapist,” he added. “I’ve found this really cool therapist. It’s great and perfect for me right now. Hopefully, it continues to be the case. It’s helped me a lot. After doing press yesterday, I had another session, and it was amazing,” he continued. “It helps you unlock things about yourself. It’s not even necessarily about the person that you’re doing therapy with, but like you said, perspectives and strategies and tools that you didn’t have access to before.”
