As it's the fifth year anniversary of Skyfall, film website BirthMoviesDeath have looked back at the film and unearthed some little-known trivia in doing so.
According to their article, the 23rd Bond film had a treatment (the step between a sketched out plot and screenplay) which would have given viewers not only a different title but a different plot.
They write, "A treatment by Peter Morgan, Neal Purvis and Robert Wade called Once Upon a Spy which finds a young M during the Cold War, having an affair with a KGB spy in Berlin. The present-day plot involves that agent’s son blackmailing M and ends with Bond being forced to kill her."
“It didn’t work,” say the involved parties, and when MGM’s situation delayed a production start, the script was tossed. Mendes and Craig faced the delay by re-reading all 14 Ian Fleming novels. Skyfall was of course its own story, but those re-reads made their way to the eventual film, which leaned heavily on elements from Fleming’s You Only Live Twice and The Man With The Golden Gun for its story.

What might have been, eh?
