Re: The last days of krypton
The story treatment that I had worked on used a lot of the material from the film and made it into flashback material, connecting the destruction of Krypton with Brainiac and his corresponding plan for Earth.
I think in a similar way that Nolan's Batman trilogy is delving into the Batman mythos and telling a complete story, we need a Superman trilogy which tells a single story stretched over three films instead of just a villain of the year version which is quite boring and predictable.
In fearful day in raging night, no evil shall escape my sight. When all seems lost and hope ignites, beware my power, Blue Lantern's light.
