Never heard the spaghetti westerns called the dollar trilogy. I knew the other titles, Fistful of Dollars and For a Few Dollars More, but just never heard that name for them. I really enjoyed this quiz and would love to see more like it.
I guessed not everybody would know the "Dollar" name, but on the other hand it's not obscure either. Thanks for your comment! I might make more of these, even if they won't cover the giant milestones of cinema anymore.
