Killers of the Flower Moon star Lily Gladstone issued a statement warning Native American audiences that the Martin Scorsese flick may be “a lot to take in” for some viewers.

After the SAG strike ended this week, Gladstone took to X to speak candidly on the film’s graphic nature and depiction of “recent history.”

“The most pressing thing I’ve wanted to say about Killers of the Flower Moon, especially to Native Women & Youth: See it when and only if you feel ready, and see it with people you feel safe with,” she wrote. “You’ll likely have a lot of generational grief to process. You’re not alone.”

Her statement continued, “Never forget this story is recent history with a lasting impact on breathing, feeling people today. It belongs to them, & we all have so much to learn from it. In this process of learning about the horrific Reign of Terror, remember that the Osage remain. Native People remain. And this story is a lot to take in. Be kind, and please be gentle with each other. There is much to process, and much to heal.”

Gladstone’s Reservation Dogs co-star Devery Jacobs recently slammed the movie for being “unnecessarily graphic” in its depiction of the Reign of Terror.

“Being Native, watching this movie was fucking hellfire,” Jacobs wrote on X. “Imagine the worst atrocities committed against [your] ancestors, then having to sit [through] a movie explicitly filled with them, with the only respite being 30 minute long scenes of murderous white guys talking about/planning the killings.” 

But Jacobs praised Gladstone and the Indigenous actors in the film writing, “Give Lily her goddamn Oscar. But while all of the performances were strong, if you look proportionally, each of the Osage characters felt painfully underwritten, while the white men were given way more courtesy and depth.”

She went on to say she didn’t feel like the “very real” Indigenous people “were shown honor or dignity in the horrific portrayal of their deaths.”

In Gladstone’s post, she shared multiple resources for Native viewers to turn to, and concluded her statement by acknowledging that she was “proud” of the film they made in collaboration with “Osage Nation leaders, artists, educators & community advocates.”

“Never forget this story is recent history with a lasting impact on breathing, feeling people today. It belongs to them, & we all have so much to learn from it,” Gladstone wrote.

Killers of the Flower Moon is now playing in theaters.
