There are a few possibilities:
* You may be thinking of a different movie title. Perhaps there is a similar title, or you're remembering a different year.
* The film could be a lost or obscure silent film. Some films from the 1920s are indeed lost or have limited documentation, making it difficult to find release information.
* The film may not exist. There might be a mistake in the title or year.
To help me find the correct information, could you please:
* Double-check the title and year. Are you sure it's "Dead Men Tell No Tales - 1920"?
* Provide any other details you remember. This could be the genre, actors, or even a brief plot summary.
* Tell me what kind of information you need. Are you looking for the release date in a specific country?
With more information, I can help you find the film's release details.
