No, this "lost" Charlie Chan movie hasn't been found. Just a heads-up that Wildside Press is publishing the screenplay for Charlie Chan's Chance as a trade paperback book, formatted for easy reading. We will follow up with the screenplay for Charlie Chan's Greatest Case 2-3 weeks later.
I really enjoyed working on this one, and as a Chan fan, I can attest that it was a strong entry in the series. Alas, it was Warner Oland solo (no Keye Luke). But still very good.
