In the 1990 movie "Pretty Woman", Richard Gere as Edward Lewis is a rich guy who is a corporate raider and womanizer. Julia Roberts as Vivian Ward is an assertive freelance hooker. She has a heart of gold and loves living in Hollywood, CA. Lewis has come from New York and he meets Vivian in LA.

After Edward and Vivian accidentally meet, he asks her to be his companion (escort). He wants her to accompany him to some important social events. This is something his prior girlfriend refused to do. To be his companion, Gere (Lewis) offers Roberts (Ward) $3,000 to stay with him for six days. He is also willing to buy her a totally new, more acceptable wardrobe. Following the changes that are made, Edward is visibly moved by Vivian's transformation. He starts to see Vivian in a very different light. He begins to open up to her, revealing personal and business facts about himself.
