read between the lines PV...this is establishing that owen doesn't approve of luke becoming a jedi like his father, and has been keeping him sheltered from the idea....it's showing the whole new previously unknown world that is opening up to luke during the film....and every time obi wan mentions luke's father, he looks shifty and chooses his words carefully, and NEVER actually reveals any real information about who his father actually was (like a name? you don't think he'd mention a name if there wasn't some big secret plotpoint they were setting up?)....
but you're right cipher, the leia thing was tacked on at the last minute....
well, i guess we're gonna have to agree to disagree on this one PV, but to me it's always been 100% obvious...i'd stake my life on it....and do you mean the original draft from 1973 when luke had 5 brothers, the deathstar was cloud city, luke was a general in the army etc. etc.....
as of shooting the film, vader was luke's father, and i wasn't even really shocked when that was revealed in esb, because it had been telegraphed so thoroughly....but before i let this lie, i would like to know who you think the big "secret father" figure they were all alluding to for a solid half hour of the film was going to be originally....
fair enough....we're not going to get much further than this i feel....but i'm 100% certain of this and i don't say that lightly, maybe next time you watch it just think about it, but there's no point repeating this over again i think....said what i had to say on the matter, and was deadly serious....peace....
