Warner Archive have just put up preorder notification for a CHARLIE CHAN TRIPLE feature that will close out their Chan holdings from Monogram. The titles are: the elusive Toler title RED DRAGON and the final Roland Winters titles, SKY DRAGON and THE FEATHERED SERPENT, which both feature the return of Keye Luke to the series. Release date is 06/07/2016.
Edit:
Sorry, I noticed that Harold already mentioned this in his Warner Archive thread!
