Pretty Woman is one of our favourite romantic comedies but as it turns out, it could have been a very different movie. The film celebrates its 25th birthday this week and original scriptwriter JF Lawton has revealed that the original story was supposed to be "dark and gritty", with Vivian and Edward not ending up together in the end. According to Vanity Fair, the movie was originally called 3,000 and was inspired by the story of hit Oliver Stone movie Wall Street. "I was a screenwriter who was trying to get a job, I was unemployed and I was working in post-production and I was trying to sell scripts, and I had been writing all of these ninja scripts and comedies, and I just couldn't get any attention. I suddenly said, 'Well, maybe I need to do something more serious and dramatic," he said. "Wall Street had either come out or was coming out, I had heard about it and the whole issue about the financiers who were destroying companies. I kind of thought about the idea that one of these people would met somebody who was affected by what they were doing." The ending of 3,000 saw "Kit and Vivian on a bus bound for Disneyland", with Kit anticipating a fun day financed by Vivian's week with Edward, as Vivian "stares out emptily ahead". However, after Julia Roberts and Richard Gere were cast in the lead roles, it was decided to take the film in a different direction. "During this whole thing, there was all this whole debate about 'How do we end it, how do we save her?' without it feeling like a cop-out. They had auditioned Al Pacino, they had auditioned Michelle Pfeiffer, and it would definitely have been a different movie if had it been Al Pacino and Michelle Pfeiffer," he continued. "It might have been closer to the original script and maybe not have had a happy ending. But the chemistry between Julia and Gere, it is palpable on the screen, it was palpable in auditions. You can't really see how it could end any other way, because they just light up with each other."
