You picqued my curiousity on the mispelling of Mr. Toler's name on the Volume 4 boxed set I received in the mail last week. I can also confirm that the covers of "Honolulu" and "Treasure Island" list "Sydney" Toler as well - at least on my copies.
Looking forward to completing my set of this excellent series.
As it turns out, my set also shows "Sydney" Toler where you mentioned. I did have time to view "Charlie Chan at Treasure Island," and was VERY pleased with the clarity! It was almost like seeing it for the first time again.
The extras that I watched were well done, and look forward to seeing more of the Ken Hanke/John Cork commentary. I suspect that it is lengthy, perhaps running through the entire film?
In March, we will be featuring all of the films from "The Charlie Chan Collection, Volume 4" for our Chat/Film Viewings. I think that it will make for a very nice month.
