Good ones. So much ridiculous (er, to me, a child of Hollywood) casting over many decades, including now.
I often have felt, at a2k and other places, like I'm the only one ever interested in "foreign" films. That's not true of course, but it seems a lot of americans aren't interested in "the other" unless he or she is a cartoon character. I was introduced to foreign films on a blind date (my mother didn't like him, he smelled of smoke), a fellow who took me out to see a Jules Dassin's He Who Must Die, and then for coffee. I was probably twenty. Let's say it wasn't love at first sight (he was somebody at work's brother, not that long before from Hungary. He was probably bemused by me.)
Topping it off, Jules Dassin was, according to wiki, born in Connecticut, but it was a French production and set in Greece.
I've spent a lot of time and almost-love for foreign films, while liking some american ones of course. The thing is, I tend to like personal stories well told, and I got more of those at the Fox Venice Theater (art film/whatever is available in film files) than I did in theaters on LA's main boulevards. Doing all that, I was introduced to other folks in the world, of whatever shade or nationality or circumstance.
Beginning film makers sometimes start small with low money and equipment and involve friends at hand. But Hollywood (and similar) don't usually reach for actors who fit the roles that are at hand, they reach for names who will pull in crowds early who might work out in the role with some tweaking.
It always has revolved around money, me thinks.
