Wow some great ideas here. My turn
Opens on a frozen wasteland, a fierce blizzard sweeping across the screen, a lone figure wonders off in the distance heading north, we close in on the figure, face coverd and feet stagering,all we see is a shining bright crystal clutched to his chest.
The blizzard dies down and the figure comes to a stop on an ice dune and looks off into the distance across the frozen tundra, focus on the figure as he removes his face wrappings "we hear the first few tones of the superman theme in a nice slow dramatic way as we reveal a young Clark Kent" he looks at the crystal, it glows, he grips it tightly the throws it at it flys straight at the camera, the fortress constructs its self and Clark enters it.
Disinbodied voices of Jor-El and Lara-El is heard and discribes some of Clarks origins, Krypton and such for the audiance.
He asks what should he do with these powers, how can he help people and still live a life with them, he recieves no answer....He shouts " Please!! What must i know!!"
Off screen we here Lara-Els voice " Kal-El, my son", Clark looks around and then his face full of suprise and he takes a step back.
The camera pans to the left and we see what had suprised Clark so, and there they stand, Jor-El and Lara-El dressed in Kryptonian formal garbs both with the Shield on there chests "at this point the intro music to SR begins (which is what i used to visualize all this)" and Joe-El says " My son, you have alot to learn" both he and Lara share a knowing smerk on there faces, we get a quick look at Clarks confused reaction and then back to his folks with and arm around Lara the camera flys straight into the sheild on Jor-ELs chest.
Now for the begining creds i always wanted to see a Flash Gorden kinda intro with comic pages flying at the screen starting from what happened with Krypton, to the Kents finding Clark, to Clark discovering his powers, Daily Planet and Superman fighting bad guys. With an intro like this the film could start from whatever point the Director wants, from a rebooted origin, to being Superman already as the intro has kinda shown what hes about. Sorry if its not so easy to see but its really clear in my head and it would look so cool. Let me know wat u think.
(Oh and also i was thinking of a stargate tunnel effect while the comic pages flew at the screen the really landmark pages stopping or slowing down to show the audiance his story).
