The latest season of Disney and National Geographic's Genius docudrama, titled Genius: MLK/X, focuses on two civil rights icons, Martin Luther King, Jr. and Malcolm X. 

In previous seasons, Genius spotlighted one historical figure, such as Albert Einstein and Pablo Picasso. 

But for Season 4, the anthology opted for what The Hollywood Reporter described as a chronological "compare and contrast essay," highlighting both the differences and commonalities between the two leaders, along with a supporting cast of historical characters.

The Cast and Characters of Genius: MLK/X

Here is the main cast of Genius: MLK/X with details about each actor and their character:

  • Kelvin Harrison Jr. - Dr. Martin Luther King Jr.
  • Aaron Pierre - Malcolm X
  • Weruche Opia - Coretta Scott King
  • Jayme Lawson - Betty Shabazz
  • Ron Cephas Jones - Elijah Muhammad
  • Lennie James - Martin Luther King Sr.
  • Gbenga Akinnagbe - Earl Little
  • Griffin Matthews - Bayard Rustin
  • Donal Logue - Strom Thurmond
  • Gary Carr - Clyde X

Kelvin Harrison Jr. - Dr. Martin Luther King Jr.

When tapped to play the visionary civil rights minister and proponent of non-violence, 29-year-old Kelvin Harrison Jr. confessed his hesitancy to Disney, saying, "I haven't lived enough" and expressed "this feeling that [he hadn't] earned it."

What Harrison Jr. has earned in recent years is an impressive list of credits, including the likes of Luce, Elvis, Cyrano, and Aaron Sorkin's The Trial of Chicago Seven.

According to the actor, he eventually accepted the role advised to "lean into" his fears and uncertainty as it would offer "a tangible take on Dr. King:"

"He also was terrified. He also had anxiety, and fear, and a sense of imposter syndrome… They said, ‘Lean into that. That is going to offer us a tangible take on Dr. King.'”

Aaron Pierre - Malcolm X

Best known for his role in 2021's Underground Railroad and M. Night Shyamalan's Old, 29-year-old London native Aaron Pierre has earned positive praise for his portrayal of the charismatic Malcolm X, a spokesman for the Nation of Islam (NOI), a champion of Black empowerment, and his civil rights ideology of "by any means necessary."

While playing Malcolm X was a huge undertaking, Pierre is poised to take on another major role in 2024, namely as the voice of Mufasa, first made famous by James Earl Jones, in Disney's upcoming prequel Mufasa: The Lion King

Weruche Opia - Coretta Scott King

Genius: MLK/X would not have been able to explore the personal lives and makeup of Dr. King, or the civil rights movement, without the influential Coretta Scott King, played by Weruche Opia. 

Born in Nigeria, Opia is best known for I May Destroy You and Bad Education.

Jayme Lawson - Betty Shabazz

To play the wife of Malcolm X, Jayme Lawson told Disney about her research and how Before Betty X, a children's book written by Betty's daughters, is how she "found" her portrayal:

“And the moment I got that book, I said, ‘I found her,’ because I found the little girl. And as a woman, I think we all carry the little girl into every room we walk into.”
