Henry Byron Warner (often credited as H.B. Warner) was an English actor. He was the definitive cinematic Jesus Christ in Cecil B. DeMille's The King of Kings (1927). He was born into a prominent theatrical family on October 26, 1875 in London. His father was Charles Warner, and his grandfather was James Warner, both prominent English actors. He replaced J.B. Warner as Jesus in The King of Kings (1927) when J.B. died of tuberculosis at age 29. (J.B. was not Henry's brother. J.B. had taken the professional last name "Warner" because Henry's family took him in.)

Henry Warner's family wanted him to become a doctor, and he graduated from London University but eventually gave up his medical studies. The theater was in his blood, and he studied acting in Paris and Italy before joining his father's stock company, making his debut in the English production of "Drink." It was from his father that he honed his craft.
