Collider.com reports that an individual claiming to be a visual effects supervisor for Zack Snyder's upcoming reboot, "Man of Steel" has posted the following information on IMDB which supposedly describes scenes from the film:

Last night at a VFX conference there was a sizzle reel shown by Weta. In this sizzle reel there were two beta level(most likely from a trailer) clips shown. One only about 6 seconds long, the other much longer.

The former was Clark Kent grabbing a truck with a crying man inside of it while flying through the middle of a tornado. It looked incredible. Henry Cavill can fly, and he can hold a truck in one arm. Zack Snyder brings his usual visual flair, but somehow is still unlike anything he has made before. It felt like a Superman comic. Real heroism.

The longer clip was even more stunning, but the more I think about it, slightly concerning. The clip consisted of Superman in full costume in a verbal argument with Zod in the center of Smallville with Christopher Meloni yells at them through a megaphone next to a tank. Meloni warns them he will fire if they do not surrender. While he says this Zod sizes Superman up. Shannon looks evil as he can be. Bone chilling even. And is DEFINITELY sporting enhanced muscle. Cavill’s Superman is a wonderful sight to behold in motion. Cavill’s pure size makes him the most believable Superman to date. Zod speaks in Kryptonian “Do you know your native tongue, Kal-el?” Superman looks stunned, and responds in English, “Who are you?” (there isn’t enough Superman dialogue to judge Cavill’s performance fairly, but I’d say he did well. Nothing spectacular from this clip.) Meloni curses, then into a walkie talkie orders the tank to fire. Superman hears this and turns to the tank. Zod takes this opportunity to sucker punch Superman (in Zack Snyder slow-then-fast-mo) then when the tank fires Superman rushes in front of Zod, despite the punch and catches the exploding missile near his stomach. The flames ripple around him, hit his face, his cape, his eyes. The shrapnel hits him and bounces off. The same happens to Zod to a lesser extent. Meloni’s shocked expression when they remain standing, silhouettes in a cloud of smoke, ends the clip.

It was incredible, it really was. And absolutely visually stunning, but my qualm is its typical Zack Snyder. It doesn’t look glossy like his films do. It instead has a more clean cut, colorful look. Like Thor, or Iron Man. But it is the same slow-mo styling that people expect from him. Maybe it just happens in this one scene, but it happens twice. Makes me a bit hesitant, despite the fact it looks phenomenal.

Whether or not this information is accurate or the writings of an over-zealous fan remains to be seen and should be treated as strictly rumor until any official word and/or confirmation is released by Warner Bros. or the Snyder camp.

"Man of Steel" also stars Henry Cavill as Clark Kent/Superman, Amy Adams as Lois Lane, Russell Crowe as Joer-El, Ayelet Zurer as Lara Lor-Van, Kevin Costner as Jonathon 'Pa' Kent, Diane Lane as Martha 'Ma' Kent, Michael Shannon as Zod, Antje Traue as Faora, Christopher Meloni as Colonel Hardy, Harry Lennix as General Swanwick, Laurence Fishburne as Perry White, Richard Schiff as Dr. Emil Hamilton, Cooper Timberline as Clark Kent (Age 9), Dylan Sprayberry as Clark Kent (age 13), Jadin Gould as Lana Lang (age 13) and Robert Gerdisch as Whitney Fordham (age 14).
