Here's a McHale's Navy cast photo, since you won't likely see that show on TV Land any time soon (too expensive to edit out all the "Nip" references, I guess.):
First off, who knew he was still alive? And looking great for 90 too!
Second, I think one of the reasons the older military shows, like McHale's Navy and Hogan's Heroes, or the movies like Tora Tora Tora, had a realistic "feel" to them that modern military movies don't (even though special effects are a lot better) is that practically all of the actors were themselves military veterans, most of World War II.
Think about that! There was a time when Hollywood was full of vets! Of course, during that time, Hollywood supported the country and wasn't a nest of vipers.
How many modern vets are in the movies or television?
