[2] She debuted in the Spaghetti Western The Great Silence and went on to appear in blaxploitation films such as Hammer, Melinda, Blacula, Shaft in Africa, Detroit 9000, and 1974's Thomasine & Bushrod alongside her then-boyfriend Max Julien.

She was a regular on the 1987 Universal Television situation comedy Bustin' Loose, starring as Mimi Shaw for its only season (1987–88).

[4] She enrolled at San Francisco State University to study pre-law and acted with the racially conscious Black theater group Aldridge Players West.

[5] McGee landed her first role in 1968, when she performed alongside Jean-Louis Trintignant and Klaus Kinski in Sergio Corbucci's Spaghetti Western The Great Silence, and made her first released film appearance earlier that year as the eponymous character in the Italian comedy Faustina.

Earlier that year she had appeared in a supporting role as an occult priestess in The Norliss Tapes.

The 1977 film, Brothers, in which Mcgee played a character similar to Angela Davis, was pulled from the box office because of the fear of riots.

When singer Diana Ross landed lead roles and was hailed as proof of equal opportunity Hollywood, McGee argued otherwise.
