My answer in this question:

Includes this paragraph:
So the available evidence is that the opening crawl was used for opening credits at least as early as The Plainsman (1936), and was used in a movie serial to summarize previous episodes at least as early as the Buck Rogers (1939) serial. Thus it is uncertain whether Buck Rogers (1939) was the first movie serial to use an opening crawl to summarize previous episodes.
And I was wondering whether anyone knows the history of opening crawls and can identify the first movie serial to use one to summarize previous episodes.
