With its July 22nd release date looming, it seems odd that we haven't seen a poster or a trailer for Marvel's hotly anticipated 'Captain America: The First Avenger' (although that should change after a spot runs during the Super Bowl this Sunday). However, there has certainly been no shortage of images released from the production, whether they're crude spy shots of stuntmen or glossy, studio-sanctioned releases with full color correction.

Just when you think you've seen Chris Evans in costume as the Star Spangled Avenger from every possible angle, a new series of pics crop up to prove you wrong! Join us after the jump as we take a whirlwind tour of the most recent crop of tantalizing stills from one of this summer's coolest looking movies.

'Captain America' was the cover story on the latest issue of Empire and Coming Soon snagged a few lovely shots from the magazine's interior. First, there's this dynamic hero shot, letting you observe every strap, buckle and thread of Cap's costume in all of its patriotic, Nazi-punching glory:



Then there's this image of Steve Rogers (Evans) without his trademark helmet and looking a little worse for wear:



Now, here's Rogers completely out of uniform, roughing up what we can only assume is some sort of nasty, Nazi scumbag (and anyone not sold on Evans as a superhero should take a look at his bicep in this shot because, um, whoa):



Of course, 'Captain America' isn't all muscled superheroes roughing up the forces of evil (that's only about 98% of it). Here's leading lady Hayley Atwell in action:



Finally, here's a look at operation Rebirth, the top secret military project that creates the superhuman serum that transforms Rogers from a skinny weakling into an ass-kicking crusader for the American way (it also offers us a glimpse of Tommy Lee Jones in the film):



The second batch of photographs comes from French site Les Toiles Heroiques, who have a pretty rough-looking image of Bucky, Captain America's sidekick (as well as images of Hugo Weaving's Red Skull prior to his villainous mutation and a team of HYDRA soldiers):



And speaking of Bucky, the LA Times has a clear shot of Cap and Bucky (albeit, a shot that doesn't hint at Bucky's solder antics):



Director Joe Johnston also spilled some new information about how Bucky will be treated in the film:

"We took some liberties with the relationship between the two guys ... In our story, Bucky is already in the service, he's already joined up and is being sent overseas while Steve is still struggling to get in the army. That's different than what you may have read in the comics. It adds a nuance to the relationship that pays off later. They're closer in age, too - they're virtually the same age. That's not the case at all if you go back to the old comics."

Are they setting up a darker, edgier Bucky so that his older self, the brainwashed assassin Winter Soldier, can appear in future 'Captain America' films down the road? Knowing Marvel's goal of building a larger, connected movie universe, signs point to yes.
