Katharine Parker in Working Girl
Directed by Mike Nichols, Working Girl stars Melanie Griffith as Tess McGill, a frustrated secretary struggling to forge ahead in the world of big business in New York. Co-starring with Griffith is Sigourney Weaver, who plays the role of Katharine Parker. Katharine was introduced as a supportive boss to Tess at the beginning of the movie but was later revealed to be a Machiavellian character.
In the 1988 romantic dramedy film, Tess gives Katharine an excellent business tip, but Katharine simply steals the idea without giving due credit to her secretary. In the end, Katharine is fired for fraud, while Tess is promoted to a new job as a junior executive.
