There are several movis based directly on Pride and Prejudice. One from the forties stars Greer Garson and Laurence Olivier. Another one was made about twenty years ago and stars Colin Firth and Jennifer Ehrle. the most recent one was released about five years ago and starred Kiera Knightly.
Also, the first Bridget Jones movie is based loosely on the original Jane Austen movie. In fact, I believe the main suitor, played once agin by Colin Firth is named Darcy.
