There isn't much info on Ben Carter. Not even MSN entertainment has anything but a list of his films of which are much more than three. If you check my blog (address above) I featured both Mantan Moreland and Ben Carter for the Scarlet Clue film.
So sorry you misunderstood. I never said there was just 3 films, I just said there was 3 the year he died and 3 the year before. By the way there is no mention of him in "Find a Grave" or the Ancestry site as far as I know. I don't find MSN Entertainment as a very credible source for actors and their film, certainly not the caliber of IMDb for their information.
Surfice it to say, I think he was a good actor and worked well with Mr. Moreland. Thank you so much.
There is an excellent article about Mantan Moreland at Horror-wood (mostly about his horror comedies) but it touches upon the fact Mantan and Ben Carter were stage partners. Maybe this Joe Winters who wrote the article has some info aobut Ben Carter.
Excellent site and message board BTW. I have been a Charlie Chan fan for over 40 years.
