Danielle Deadwyler admits she hesitated when it came to taking on the role of Emmett Till’s momMamie Till-MobleyinTill.
“I’ll be honest, it was the most scary thing I could think of, role-wise, to do,” Deadwyler, 40, tells PEOPLE in this week’s issue. “I neglected to read it. And I say that to show a kind of parallel to the experience of Mamie, to show that we don’t always boldly walk into things.”
Roy and Milam have since died, but Carolyn remains alive andhas not been chargedwith any involvement in Emmett’s death.
Deadwyler, who grew up working with civil rights organizations in Atlanta, felt a sense of responsibility for Emmett and his mother’s story “to be told right, and for it to be told truthfully and historically accurate,” she says. “All that was going into the feeling of saying ‘yes.’ "

Being a mom to a 13-year-old son allowed theStation Elevenstar to connect with Mamie as a parent.
Upon learning about Emmett’s murder, Till-Mobley fought to have her son’s body returned to Chicago, where she held an open casket funeral for the boy. She wanted the world to see the brutality that resulted from racism in the Jim Crow South.
“She’s bringing you into the utter and complete drudgery of what it means to be a mother who sees something happen to a loved one, a person seeing the ramifications of terrorism on her child,” Deadwyler says.

Before Emmett left for Mississippi from his home in Chicago, his mother talked to him about how he should act around white people in the South and what to expect. Deadwyler has had similar discussion with her own son and admits it can be a difficult conversation to have.
“I feel f—ed up about having to have that conversation, but I still did have to have a conversation,” she says. “I have this responsibility to inform him how to navigate the world. His social environment is very white at this time, in his school milieu. And I’ve made a point to have a certain kind of cultural upbringing for him. He’s privileged. I tell him he’s privileged in a certain way, and everyone is not.”
Deadwyler continues, “He’s very aware of the social dynamics that are happening. He’s having the conversation with me aboutUvaldeand how his peers are reacting. He’s having the conversation aboutBuffaloand not sitting into him and his body. There’s this attention in the Black experience that I know he’s understanding now. Innocence is shifting.”

The fact that Deadwyler spoke about these topics with her son, though, proves “the relevance of this film,” she says. “The expectation is to continuously rage against the machine, to continuously fight, to continuously tell these stories with a particular care and precision.”
Deadwyler hopes the Till family obtains justice for Emmett.
“That’s what they deserve,” she says. “I don’t know what it wholly looks like, but I know that it is a continuous effort on their behalf; it’ll be a continuous effort on the Black community’s behalf. It is not right to commit an egregious act against a child and suffer no consequence. Accountability has to be had. Justice comes in a number of ways, and it is yet to be seen.”
