Notes
From an interview with United Press International:

Asked if it bothered her when interviewers and announcers butchered her name, the actress replied that it doesn't anymore, but "in the beginning, it was so frustrating to me because my name is not pronounced 'There-on.' I changed it to 'There-on' because I was told it was more American. So, that was what was frustrating! The fact that I changed it to make it easier, so that people could pronounce it and then people kept going 'There-own.' The way we pronounce it in South Africa is 'Thrown.'
