Chadwick Boseman’s Unshakable Commitment on ‘Black Panther’ Set Left Disney Execs Stunned: “He Don’t Turn It Off Until We Wrap”

Chadwick Boseman’s legacy as an actor continues to inspire not only fans but also the people who had the honor of working alongside him. Director Ryan Coogler recently shared powerful insights into Boseman’s intense dedication to his craft during an interview on The Breakfast Club, particularly recalling the late actor’s transformative work on Marvel’s Black Panther.

According to Coogler, Boseman’s embodiment of King T’Challa wasn’t limited to when the cameras were rolling. From day one of shooting, Boseman spoke exclusively in T’Challa’s Wakandan accent—even during off-camera moments. This level of immersion didn’t go unnoticed, especially by some visiting Disney executives early in the production.

“He was talking in an African accent,” Coogler said. “Disney execs came to see us on ‘Panther.’ It was week two and they pulled up and it was the T’Challa accent and they were freaked out. I was like, ‘Don’t be freaked out. He’s working, man. He don’t turn it off until we wrap.’”

Boseman’s steadfast approach was emblematic of who he was both on and off set. Coogler, who is currently promoting his upcoming film Sinners, revealed how deeply Boseman’s discipline affected those around him—especially Black Panther co-star Michael B. Jordan.

“Out of all of my actors, Chad’s death actually hit Mike the hardest,” Coogler said. “He was a fully baked man from the South. He was an old school man’s man… Me and Mike, we were kids next to him.”

Coogler reflected on Boseman as a mentor-like figure—someone who led through action and grace, never seeking attention or acknowledgment for the quiet lessons he imparted.

“He changed my life. He was the kind of teacher you never knew was giving you a lesson when he taught. It was all by example,” Coogler said. “He was always early. He moved at an old-school pace and took his time. That’s what he gave me and Michael: patience.”

Coogler also revealed how Boseman’s influence extended into his latest project. While working on Sinners, he often asked Michael B. Jordan to think about how Boseman might have approached a role, pushing for a level of immersion and commitment that mirrored Chadwick’s.

Boseman passed away in August 2020 after a private battle with colon cancer, leaving behind a legacy that’s as much about integrity and intention as it is about art. For Coogler and those who worked closely with him, that legacy remains a source of inspiration.

“Sinners” opens in theaters April 18.
