The release date of a film is not a typical search term. On the other hand, movie titles, names of actors involved, and names of directors are the common ones. Unless the year appears in the movie description itself, it will not be the best approach to track down a film through a simple search.
However, since you have the title of the film, "Key Largo," enter it into the search box above. The results will show every possible information available on this title on Jaman, whether it's the movie itself or discussions about the film. If there's a trailer for it, that will appear as well.
In this case, "Key Largo" is not part of the Jaman library. However, there are many other titles from this era if you are interested in Hollywood classics. Be sure to check the Classics genre under the Movies tab.
Since you are relatively new to Jaman, I would encourage you to browse through the following pages to get better acquainted with the site:
