Cast

A brilliant mathematician at NASA, Katherine Johnson specializes in calculating complex flight trajectories. Her precise work is critical for the success of the first American orbital spaceflights, particularly John Glenn's mission. She faces and overcomes significant racial and gender barriers in her pursuit of excellence. 

A pioneering mathematician and the supervisor of the West Area Computers division at NASA. She anticipates the shift to electronic computers and teaches herself and her team programming, becoming an expert in FORTRAN. Her leadership and foresight ensure that her team remains indispensable to NASA's operations. 

A talented mathematician and aspiring engineer, Mary Jackson fights against societal norms to become NASA’s first African-American female aerospace engineer. She takes night classes and petitions the court to attend an all-white high school. Her determination paves the way for future generations of women and minorities in STEM fields. 

The no-nonsense director of the Space Task Group at NASA. He is focused on results and breaks down racial barriers within his team to ensure that the best talent, like Katherine Johnson, can contribute to the mission. Harrison’s support helps Katherine gain the recognition she deserves. 

An engineer at NASA who is skeptical of Katherine Johnson's abilities. He initially undermines her efforts but eventually comes to see the value of her contributions. His resistance and eventual acceptance highlight the challenges and triumphs of integrating a racially diverse team. 

Colonel Jim Johnson is Katherine’s supportive husband. Initially skeptical of her role at NASA, he soon appreciates her brilliance and supports her career. His encouragement strengthens Katherine’s resolve to excel in her work. 

Levi Jackson is Mary Jackson's supportive husband. He stands by her decision to pursue an engineering career despite the societal challenges they face. Levi represents the supportive family backbone that helps Mary achieve her dreams. 

A supervisor at NASA who initially enforces segregation policies. Over time, she begins to recognize the talent and dedication of the African-American women under her supervision. Her character illustrates the gradual shift in attitudes towards racial equality within the workplace. 

John Glenn is the astronaut whose mission is made possible by Katherine Johnson’s calculations. He shows trust and respect for her work, insisting on her confirmation of the flight calculations. Glenn’s faith in Katherine highlights the critical importance of her contributions to the space mission. 

Works as Al Harrison's assistant in the Space Task Group.

Karl is a Polish engineer at NASA who encourages Mary Jackson to pursue an engineering career despite societal barriers. 

Sam is an engineer at NASA who works alongside the main characters on various projects. 

Young Katherine, whose exceptional math skills are evident from an early age. 

She is Katherine's eldest daughter, who supports and motivates her mother through her academic and professional journey. 

Another of Katherine's daughters, who is proud of her mother’s achievements and looks up to her as a role model.
