Someone (well this guy Tom F) made some modern remixed trailers for the original Star Wars trilogy. And it looks pretty awesome with that great song John Williams composed for The Force Awakens trailer (which sadly WASN'T in the new film's lackluster soundtrack - my only real complaint about the film personally!).
Check them out, they're awesome, well made and well worth your while!
Y...eah. Watching these like this, I noticed I really prefer the originals over the new film, no dish against Abrams though.
