No trailers or even teaser posters yet, but it's basically the revamp of Superman after the last one failed to impress. It's got Zac Snyder (300, Watchmen), Chris Nolan (The Dark Knight, Inception) and David S. Goyer (wrote The Dark Knight, the Blade trilogy) as the production team.
As for the acting talent, Amy Adams (Enchanted, The Fighter) will play Lois Lane, Henry Cavill (quite unknown... was in Stardust) as Superman. Diane Lane, Kevin Costner, Michael Shannon, Antje Traue and Henry Lennix also feature - and Russell Crowe is negotiating.
Storywise they're ignoring Lex Luthor this time
General Zod and Faora are those featuring.
