I've said before that throughout the 1990s, romantic comedies were extremely popular. Of course, this is not to say that romantic comedies were not popular at other times; it's just that the '90s produced quite a few notable romantic comedies, the most famous of which was Julia Roberts's quartet of love stories. Essentially, Julia's status in Hollywood was largely owing to these four outstanding romantic comedies.
Especially since these four characters, though greatly different, shared one consistent trait: independence, strength, and confidence. It was precisely because of this that Julia became—yes, without a doubt, America's most popular actress, reaching a peak that many other actresses could not attain.
