In one 1995 interview in “Late Night with Conan O’Brien”, Thompson was asked about the big roles she missed in her career. Thompson said she was preparing for the role of Vivan Ward in “Pretty Woman,” but the audition didn’t go as planned. The actress explained:
“I read the script and it was a tragedy. I just thought this was a documentary about the pitfalls of being a pedestrian on the streets of LA. So I did the real audition. this fierce, I didn’t know it was a comedy, I was really intense, you know, in tears and a little bit more, and then I got a call from the agent, ‘You know it’s a comedy?’ “
Thompson said she was shocked when she saw the film and it was different from her interpretation. “Well, wrong acting choice,” she joked to O’Brien.
This approach turned out to be a mistake that could cost Thompson his life. But here’s the thing – her interpretation isn’t far from the original screenwriter’s vision for “Pretty Woman.”
