As Warner Bros. and Legendary Pictures amp up the promotion for Zack Snyder's "Man of Steel," a fourth trailer has been released, expanding on the Zod-centric teaser released in mid-April. Featuring a voiceover from Michael Shannon's despotic Kryptonian general, the trailer features new footage, including a marked increase in big action scenes, glimpses of technology from Superman's homeworld and more Lois Lane, Perry White and, of course, Zod and his lieutenant, Faora.

A young boy learns that he has extraordinary powers and is not of this earth. As a young man, he journeys to discover where he came from and what he was sent here to do. But the hero in him must emerge if he is to save the world from annihilation and become the symbol of hope for all mankind.

The film also stars four-time Oscar nominee Amy Adams ("The Master") as Daily Planet journalist Lois lane, and Oscar nominee Laurence Fishburne ("What's Love Got to Do With It") as her editor-in-chief, Perry White. Starring as Clark Kent's adoptive parents, Martha and Jonathan Kent, are Oscar nominee Diane lane ("Unfaithful") and Academy Award winner Kevin Costner ("Dances With Wolves").

Squaring off against the superhero are two other surviving Kryptonians, the villainous General Zod, played by Oscar nominee Michael Shannon ("Revolutionary Road"), and Faora, Zod's evil partner, played by Antje Traue (upcoming "The Seventh Son"). Also from Superman's native Krypton are Lara Lor-Van, Superman's mother, played by Ayelet Zurer ("Angels and Demons"), and Superman's father, Jor-El, portrayed by Academy Award winner Russell Crowe ("Gladiator"). Rounding out the cast are Christopher Meloni (upcoming "42") as U.S. military man Colonel Hardy, Harry Lennix ("State of Play") as General Swanwick, Michael Kelly ("The Adjustment Bureau") as Steve Lombard, and Richard Schiff (TV's "The West Wing") as Dr. Emil Hamilton.
