Having watched the trailer to Tom Cruise's award winning film Last Samurai several times I feel qualified to continue this discussion.

Basically Samurai were these guys in olden times with swords that would cleave jerks in twain with a single swipe. They also launched a rocket that went all the way to the moon.
I think Tom Cruise was based on a historical figure of the same name that was in charge of all the samurai or something. After the film he went on to create the Kobra Kai school of Karate which was featured in the Oscar nominated film Karate Kid.

Hope this helps clear up some of the confusion.
