Rush and Virginia -- Thank you, but I made an error. Correction: Lon Chaney Jr. worked with Sidney Toler, not Warner Oland. I'm getting my Chan pictures mixed up. Cheers!!! -- Steve
Re: Boris Karloff Vs. Warner Oland . . . Quiz TIme!
The way the question was worded with 'apart from the Chan series' sort of negates this answer, but another point of comparison is that both played Chinese detectives in the movies with Oland as Chan and Karloff as Mr. Wong (with Keye Luke taking over this role for one movie serving as another point of connection).
Re: Boris Karloff Vs. Warner Oland . . . Quiz TIme!
And there's more similarities between Karloff and Oland. (1) Both actors were born in a foreign country, but achieved their great success in the USA. (2) Both actors died in their respective home countries, i.e.: Karloff in England and Oland in Sweden. (3) Both actors appeared in films with the beautiful Myrna Loy. (4) Both actors appeared in films with the equally beautiful Valerie Hobson.
So what do I win? A free trip to Sweden? Or England? I'll settle for Texas.
