From the New York Times:
Vonetta McGee, a film and television actress originally known for blaxploitation pictures like “Blacula,” “Hammer” and “Shaft in Africa,” died on July 9 in Berkeley, Calif. She was 65 and a Berkeley resident.
The cause was cardiac arrest, said Kelley Nayo, a family spokeswoman.
In “Blacula” (1972), Ms. McGee portrayed the love interest of Mamuwalde (William Marshall), an African prince who, after an ill-fated trip to Transylvania centuries earlier, re-emerges in modern Los Angeles as a member of the thirsty undead.
