She later became well known for her parts in the 1972 Blaxploitation films Melinda and Hammer. In the action thriller Shaft in Africa (1973), McGee took the role of Aleme, the daughter of an emir, who teaches John Shaft (Richard Roundtree) Ethiopian geography. In 1974, McGee appeared as Thomasine, alongside Max Julien as Bushrod, in the western action film Thomasine & Bushrod, which was intended as a counterpart to the 1967 film Bonnie and Clyde. The next year, she starred alongside Clint Eastwood in the action thriller The Eiger Sanction (1975). She appeared in an episode of the TV series Starsky & Hutch named “Black and Blue” in 1979. McGee was in a live-in relationship with Max Julien during the early-to-mid 1970s. In 1987, McGee married actor Carl Lumbly. They had one child, Brandon, born in 1988. McGee died of cardiac arrest on July 9, 2010, at the age of 65.
