The fourth theatrical trailer for Man of Steel does what no previous trailer for the Superman reboot has done yet, setting up a legitimate threat to the mightiest superhero around, and showing off just how mighty these Kryptonians look in action.

Warner Bros. has taken a very strange step in the selling of Man of Steel, releasing a calendar entitled "Beefcakes of Krypton."  Naturally, this calendar features a bunch of slabs of Y-chromosomal meat on display.

Wait, calendars generally cover more than three months?  And include each day of each month organized into a grid?  Oh.

So there's no Kryptonian Beefcake calendar.  These are actually the first three character posters for Man of Steel.  That makes more sense.  But still, there are three masculine guys represented, with Henry Cavill, Russell Crowe, and Michael Shannon all looking regally Kryptonian while getting some good lens flare going.

"Superman is the most powerful, but also the most vulnerable superhero you can imagine," director Zack Snyder says in a new featurette packed with previously unseen footage from next month's Man of Steel.

In addition to a featurette mixing insight-nuggets from the cast and creative figures with action-packed super-footage, Warner Bros. and Legendary Pictures have also unveiled two new banners for the reboot, one featuring Henry Cavill zipping through the sky as Superman and the other showing his nemesis General Zod barreling towards our hero.

As of today, we are one month out from the domestic release of Man of Steel.  And we're marking this occasion with a bumper crop of promotional material from the theatrical reboot of superhero among superheroes.

Unlike, say, Cyclops, Superman has a boatload of powers and abilities.  That boatload of superpowers is reflected today in the variety of varying goodies, from an action-packed and messianic TV spot through three featurettes and up to a propulsive full track from the musical score by Hans Zimmer.

The latest TV spot for Man of Steel ladles on the messianic imagery even harder than its predecessors, but gives Russell Crowe a break from gravitas duty. 

It's a stunner nonetheless, and its accompanied by yet another poster, one that should go at least a little way towards making you believe a man can fly.

After playing stingy with Man of Steel posters during a hype season that has seen movies like The Hangover Part III getting fifteen – fifteen! – one sheets, Warner Bros. is now letting the supercat of the superbag, with two new posters for next month's Superman reboot.

Look! Down on your screen!  It's a bird.  It's a plane. 

It's a Man of Steel TV spot from across the pond in the United Kingdom!

So Iron Man is currently sitting atop a giant pile of money, but Superman is flying back into theaters next month, and if the third TV spot for Man of Steel is any indication, this hero will be facing far bigger foes than the Mandarin.

2013 is a good year for superheroes with flowing red capes.  There's another Thor arriving in November – the teaser for that one even included a cape gag in the Marvel logo – but first we have the return of the superheroic grandpappy Superman with this summer's Man of Steel.

A brand spanking new banner for the reboot puts Henry Cavill not front and center, but instead positions Supes front and off to one side, with his crimson cape taking up most of the image.

The teaser poster for Man of Steel, unveiled late last year, had Superman in an unfamiliar position: bound in handcuffs, with some serious military men flanking him.

On the official one sheet, however, Superman is unchained and taking to the skies above Metropolis at what appears to be breakneck speed.
