Khalsa, Samurai and the Jedi

Ok, I was thinking about this and because of the recent movies I have just watched, some for the umpthteen time! I came to the conclusion that these three groups have a lot in similar, they are all well disciplined and have a code of conduct that they follow which is also similar! Now I dont know much about the Samurai apart from the movies I watch which could be full of lies! So I would appreciate some knowledge on them, especially when they were formed? Is George Lucas a Sikh in terms of his thinking? I then thought Im the weirdo who tries to link every Hollywood war movie to Sikhi, but I did a search on the net and I am not alone, why hasnt some big money hollywood director heard of the Sikh history and not made a movie on it yet, Im talking after the Gurus, like from Banda Singh Bahadur to Maharaja Ranjit Singh, it would probably have to be in 5 volumes, which is in now anyway! There would be loads of battle scenes, emotion, betrayal, love (humanity), sacrifice etc etc it would be sooo cool!
