We would be doing you a massive disservice if we didn't include another Julia Roberts success. But this isn't just any old success, it's one of the most popular romantic comedies of all time! Pretty Woman is so big, it even has its own song. Released in 1990, it became the third highest-grossing film of the year. The film's male lead is, of course, Richard Gere.
The story follows businessman Edward Lewis (Gere) who hires escort, Vivian Ward (Roberts) to accompany him to several work functions and social events over a week-long period. Of course, it's not all that simple, and the two begin to develop feelings for each other. Obviously, there's a bit of drama here and there, but ultimately, they figure it all out. The film was a critical and commercial success, and Julia Roberts even won a Golden Globe for her performance.
