Great Scott! The Superman 75th Anniversary Man of Steel short has made its way online after debuting at this past weekend's NYCC!
It's a homage to the 75 years of Superman and uses both the John Williams music score and the Hans Zimmer Man of Steel score.
Director Zack Snyder came up with the idea with Geoff Johns and Bruce Timm involved as well.
The Superman short originally debuted at EW.com.
