I don't know if you consider this movie obscure or not.

But it is very hard to find. It's never shown on television.

The name of it is "MississIpippi Gambler" starring Tyrone Power and a cast of great supporting character actors.

A very complicated story that takes place in New Orleans and on a river boat.

About gambling and when people solved arguments at a drop of a hat by duels with guns and swords.

As you may or may not know Power was one of the best swordsman in of any actor in Hollywoid at the time next to Basil Rathbone.

I thought the story was great. So if you can find it get it.
