How many sequels of movies did they make in the golden age of movies? Not that many. I’m aware of the Cavalry pictures with Wayne. But imagine sequels of Gone With the Wind, or Modern Times, or Some Like It Hot, the list could go on and on. But they had good writers in those days and a lot of creativity and competition among the studios. These days the movies are dull and uninspiring.
They didn’t make a lot of sequels to the big films we remember but they did make film series. Think: Bowery Boys and such where they made multiple films using the same characters.
