Deric McCabe is a nine-year-old actor who gained fame for his role as Charles Wallace Murray in Ava DuVernay‘s on-screen adaption of A Wrinkle in Time.

McCabe shares how his character had to help find his father, alongside his sister, Meg (Storm Reid) in the film. “His father got lost in the different dimensions in time and they have to go on a journey to the same places to find him,” McCabe explains in an exclusive interview with uInterview.

While he has had a few small roles before being casted in A Wrinkle in Time, McCabe never really worked with big name actresses before. He even admits to not know who Oprah was before meeting her. “I didn’t know who they were, but they were really nice,” he says. “My mom said she’s some talk show host who gave out cars to people.”

After the last cut of filming, McCabe was “sobbing on the floor,” but Oprah reassured him that “there’s more to come.”

McCabe also has simple advice for fellow child actors, and that’s to “keep the faith.” At one point, he was not getting any bookings, but he “kept the faith” until he was chosen out of thousands of other actors for the role as Charles Wallace.

Who is your character in the movie?

Deric McCabe: My character is Charles Wallace, he’s the brother of Meg and they both lost their father. So his father got lost in the different dimensions in time and they have to go on a journey to the same places to find him, and on the way, Charles Wallace gets meaner. So yeah, that’s all I can tell you.

What was it like to meet Oprah?

DM: I didn’t know who they were, but they were really nice. My mom said she’s some talk show host who gave out cars to people. She did say there’s more to come when Ava yelled the last cut and I was here sobbing on the floor saying “No there’s not, my life is over” and everyone’s staring at me like I’m crazy.

What was Reese Witherspoon like?

DM: She just told me she was a child actress and if there is anything I need on set, to just ask her.

What advice do you have for other child actors?

DM: They need to keep the faith, because at one point I wasn’t booking anything, but yeah I kept the faith.
