The IMAX 3D trailer for this film looked pretty good. I cannot tell you the last time I paid cinema money to see a film with Costner in it, but I might have to see this one on the second or third weekend. I never heard the story about the S not being an S as in superman. In the movie trailer, superman said it was a symbol for something from his homeland. I forget what, but it was something like eternity or courage.
