Weight changed her surname to Waite. She portrayed the title character in the film Joanna (1968), which tells the story of a young art student in London in the swinging 1960s who gets involved with a black nightclub owner (played by Calvin Lockhart). Because it showed an interracial relationship at a time when it was still illegal in some places, like Waite's home country of South Africa, which at the time still under apartheid, the movie caused controversy.
