Union felt that she had been "blessed" with her role in the film, feeling it elevated her career.
She appeared in the 2005 film Neo Ned, costarring Jeremy Renner and portraying an African-American woman with delusions that she is Adolf Hitler.
In an interview with Art Nouveau Magazine, Union complained about the lack of roles for black actresses and actors in Hollywood: "There used to be [roles] specifically written black, if you knew Denzel was doing a movie you knew his wife, girl or love interest was going to be black [but] that's not necessarily the case anymore.That was like the biggest star-struck moment I've probably ever had in my life. Other earlier roles included teen movies such as 10 Things I Hate About You, She's All That, and Love & Basketball.But it's because I grew up in a household that always talked specifically Cornhusker football and Big 8 sports, at the time." She later successfully sued Payless for negligence, alleging that the store failed to warn employees about the assailant, who had been positively identified robbing another Payless location prior to her rape. In 1997, Union appeared in the sixth-season episode of Star Trek: Deep Space Nine—"Sons and Daughters" as the Klingon N'Garen. She began her career in the 1990s, appearing on television sitcoms, before landing supporting roles in teenage comedic films She's All That and 10 Things I Hate About You (1999).Her breakthrough role was in the 2000 film Bring It On.
