William Horace Marshall (August 19, 1924 – June 11, 2003) was an American actor, director and opera singer. He played the title role in the 1972 blaxploitation classic Blacula and its sequel Scream Blacula Scream (1973), and appeared as the King of Cartoons on the 1980s television show Pee-wee's Playhouse and as Dr. Richard Daystrom on the Star Trek television series. He was 6‘5” (1.96 m) tall and was known for his bass voice. Biography Early life Marshall was born in Gary, Indiana, to Vereen Marshall, a dentist, and Thelma (née Edwards). He attended New York University as an art student but transferred to the Actors Studio to study theater. He studied at the American Theatre Wing and with Sanford Meisner at the Neighborhood Playhouse. Career Marshall made his Broadway debut in 1944 in Carmen Jones. In 1950, he understudied Boris Karloff as Captain Hook in the Broadway production of Peter Pan. He played the leading role of De Lawd in the 1951 revival of The Green Pastures, a role he repeated in 1958 in a BBC telecast of the play. He performed in several Shakespearean plays on the stage in the U. S. and Europe, including the title role in at least six productions of Othello. Harold Hobson of the London Sunday Times praised Marshall’s portrayal as "the best Othello of our time." In 1968, Marshall joined the Center Theatre Group at the Ahmanson Theatre in Los Angeles to play Othello in a jazz musical version, Catch My Soul, with Jerry Lee Lewis as Iago. Marshall portrayed Paul Robeson and Frederick Douglass on stage. He researched Douglass's life extensively, and in 1983 produced and played the lead role in Frederick Douglass: Slave and Statesman. Film and television career Marshall's career on screen began in the 1952 film Lydia Bailey as a Haitian leader. He followed that with a prominent role as Glycon, comrade and fellow gladiator to Victor Mature in the 1954 film Demetrius and the Gladiators. His demeanor, voice and stature gave him a wide range, though he was ill-suited for the subservient roles that many black actors of his generation were most frequently offered. He was a leader of the Mau-Mau uprising in Something of Value (1957), and Attorney General Edward Brooke in The Boston Strangler (1968). He probably received the most notice for his role in the vampire film Blacula and its sequel Scream Blacula Scream.
