The upcoming Zack Snyder (and co-writer/producer Christopher Nolan) Superman reboot has released TWO official trailers today. The spots are essentially the same, but feature different voice-overs: one from Superman's real father Jor-El (played by Russell Crowe) and another by his adoptive farmer father Pa Kent (played by Kevin Costner).
