The Undiscovered Planet of Quazoom
Could it be? The genesis of Star Wars, in an old copy of Vogue magazine? It does indeed seem so.
Before Obi-Wan sensed the destruction of Alderaan across the gulf of space, Spock sensed the deaths of his fellow Vulcans.
From the opening of The Immunity Syndrome, episode 18 of season 2, of Star Trek the original series, first broadcast in 1966, Spock senses the deaths of 400 vulcans across the gulf of space.
This is one of those supposed influences which has no further proof to substantiate it. It seems entirely reasonable to assume that Lucas had watched the original Star Trek series in the mid-60s when it was airing, and though he never talked about it, it seems just as reasonable to assume that it indeed lay the foundation for much of the thinking behind taking on science fiction/fantasy with Star Wars in the first place.
Regardless, like most of the other more spiritual, almost slight-of-hand-like tricks exhibited by Obi-Wan Kenobi in the first film as proof of the force, this one too is nowhere near the superhuman-like abilities the later films would reach for.
WWII was an enormous influence on all kids of the 50s and 60s, and Lucas was no exception. From the general good vs evil nature of the conflict to the specifics of war epics like The Guns of Navarone and air-heroics of The Dam Busters and 633 Squadron, it seems entirely possible that Star Wars would never have existed if not for the war.
When it was first released in 1956, John Ford's latest western The Searchers didn't set the world on fire. But it wasn't long before it started its long crawl back into the limelight. And by the late 60s a new generation of film makers, including George Lucas, found renewed inspiration in it.
