I am fascinated by duels. I often wonder how it would be to depict duels in a movie that is set in modern-day. I came across an article on the rationality of duels written by an Amherst economics professor. Apparently engaging in duels is a rational act for those living in a society where credit markets are non-transparent and highly personal in nature. In other words, if one fails to pay back a loan, he is compelled to defend his honor or face the prospect of not being able to get another loan again.
