About twenty minutes from the end, though, I sat bolt upright as a thought struck me. "I know how this is going to end", I thought. And I was wrong. As it turns out, I knew how it should have ended.
So; closing reel. The big battle in space providing cover whilst our plucky heroes have to get the Death Star plans off planet, the transmission made, the sequence as the Empire tries to stop the rebels escaping with the plans. The Tantive IV makes its jump to lightspeed with Vader in pursuit and fade to black...
And then, as the close, before the credits roll...
"It is a period of civil war. Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire.
During the battle, Rebel spies managed to steal secret plans to the Empire's ultimate weapon, the DEATH STAR, an armored space station with enough power to destroy an entire planet.
Pursued by the Empire's sinister agents, Princess Leia races home aboard her starship, custodian of the stolen plans that can save her people and restore freedom to the galaxy...."
That's how it should have ended, and would have done if I'd written it.
