James Earl Jones
Before he was Darth Vader in Star Wars, even before he was nominated for an Oscar for his role in The Great White Hope, James Earl Jones played doctor. Soap opera doctor, that is! First he was Dr. Jerry Turner on As the World Turns and then Dr. Jim Frazier on The Guiding Light, both in 1966. Many fans recognize his deep voice from his famous line in Star Wars, when he said to Luke Skywalker, "I am your father." But in 1966, he was probably warming up that voice with lines like "Where's my stethoscope?"
