What is David Ajala famous for?

Early life and background

David Ajala was born on 21 May 1986 in Hackney, London to Nigerian parents. He grew up in the British capital and developed an interest in acting early, later training and performing with the Royal Shakespeare Company at the Courtyard Theatre in Stratford‑upon‑Avon (All American Speakers, speaker bureau bio).

Breakthrough roles

Ajala’s first on‑screen credit was an uncredited appearance in The Dark Knight (2008) (IMDb, industry film database). He followed that with supporting roles in British indie films such as Kidulthood, Adulthood, and Brotherhood, as well as the critically acclaimed prison drama Starred Up (2013) (Rotten Tomatoes, film review aggregator). In the same year he appeared in the blockbuster Fast & Furious 6 and later in Jupiter Ascending (2015) (Rotten Tomatoes).

Notable television appearances

Ajala’s US television breakthrough came with a lead role in the USA Network series Falling Water for two seasons (All American Speakers). He also starred in Syfy’s Nightflyers, based on a George R.R. Martin novel, as Captain Roy Eris (Wikipedia). However, he is best known for playing Manchester Black on Supergirl (2018‑2019) and Cleveland “Book” Booker on Star Trek: Discovery (2020‑2024). His upcoming role in Law & Order: Organized Crime is set to bring him back to network television.

The upshot

Ajala has successfully straddled British indie cinema and American genre television. His casting in Star Trek: Discovery made him a recognizable face for sci‑fi fans, while his past work with the Royal Shakespeare Company demonstrates a theatrical foundation that few actors in his peer group can claim.

The implication: His career path deliberately mixes stage training with mainstream TV, a pattern that broadens his range rather than narrowing it.

Is David Ajala married?

Personal life

David Ajala keeps his personal life private. He is reportedly in a relationship with Terri Martin, though neither party has made a public confirmation. No official records of marriage or children are available.

Relationship with Terri Martin

Rumors about Ajala and Martin surfaced on social media and gossip platforms, but no credible source — including Wikipedia, IMDb, or mainstream entertainment outlets — has verified the relationship. Ajala has not commented publicly on his romantic life.

What to watch

Because Ajala shares very little about his private life, any “confirmed” relationship status is speculative. Readers should treat reports with caution until a primary source (such as a statement from the actor or a reputable interview) emerges.

The catch: Without a public statement, the relationship remains unverified gossip, not journalism.

What is David Ajala’s ethnicity?

Family background

According to Wikipedia (the free encyclopedia), David Ajala was born in Hackney, London to Nigerian parents. He is of Nigerian descent.

Heritage

Ajala’s Nigerian heritage has occasionally been highlighted in media profiles, but he has not specified his ancestral region or tribe within Nigeria. His accent and upbringing are evidently London‑English.

How do you pronounce David Ajala?

Pronunciation guide

The correct pronunciation of David Ajala is /dɑːˈviːd əˈdʒɑːlə/. The first name is standard English, and the last name rhymes with “Dahlia” — a‑JAH‑la.

Common mispronunciations

Many English speakers mistakenly stress the first syllable (“AJ‑uh‑la”) or soften the “j” sound. The “j” in Ajala is pronounced like the “dg” in “judge,” and the final “a” is a schwa or an open “ah” sound.

Is David Ajala in Star Trek?

Role as Cleveland Booker

Yes — David Ajala played Cleveland “Book” Booker in Star Trek: Discovery from season 3 through the series finale in 2024. The Movie Database (community‑curated film database) lists his character as a courier who becomes a close ally of the USS Discovery crew.

Connection to Saru and Discovery

Booker’s relationship with Saru (played by Doug Jones) evolves into a deep friendship. The distinctive walk of Saru — often asked about by fans — is due to prosthetic makeup and the character’s biology as a Kelpien, not the actor’s own gait. Ajala’s Book provides a grounding human (and sometimes non‑human) presence.

Other roles: Supergirl and Law & Order

  • Manchester Black in Supergirl (2018‑2019) — a British anti‑hero from the comics (Wikipedia, the free encyclopedia).
  • Upcoming role in Law & Order: Organized Crime (2024‑) — Ajala will join the cast of the Dick Wolf franchise.
The trade‑off

Ajala’s move from the canceled Star Trek: Discovery to a network procedural gives him a chance to reach a broader audience, but it also means leaving the expansive sci‑fi universe that made him a fan favorite.
