Gladstone said when she told her grandmother she was going to be in \"Killers of the Flower Moon\" her grandmother was familiar with Scorsese and De Niro -- but not so much with DiCaprio.

\"'Who?'\" she recalled her grandmother saying. \"So I pulled out 'Titanic.'\"

Gladstone took to social media earlier this month when the SAG-AFTRA strike ended to speak about the film for the first time and to share what it means for Native Americans.

\"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. You'll likely have a lot of generational grief to process. You're not alone,\" she began, going on to share a series of \"safe, culturally specific and anonymous 24/7 resources available\" for those who need to unpack the film but have no one to speak to.

\"I'm so proud of the film we made with so many 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,\" she continued. \"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.\"

DiCaprio, too, believes this film is important viewing.

\"The story is a microcosm for many other stories about the persecution of Native Americans,\" he said. \"But look, this is still going on today.\"

\"Killers of the Flower Moon\" is now in theaters.
