Yes, very much so. Lucas himself said he was Buddhist (not sure which branch though)
Jedi are Buddhists in space. The whole ''attachemtn is forbiden'' is the one of the centre of Buddhist beliefs. In fact most of what Yoda preaches is one way or the other in Buddhist theology.
Also -the whole ''becoming one with the force after they die'' thing is tied with 'becoming one with everything' and the sense of self-lessness.
Basically Jedi are buddhist X-men in space
I think I count partly a Jedi since Im a Buddhist. Beware the awesome power of lil b!
