There were plenty of hidden details in the trailer for The Avengers , but which were most interesting and what do they tell us about the movie? Did you spot Stark Tower? Hit the jump for that and more...

Continuing the epic big-screen adventures started in "Iron Man," "The Incredible Hulk," "Iron Man 2," "Thor," and "Captain America: The First Avenger," "Marvel’s The Avengers" is the super hero team up of a lifetime. When an unexpected enemy emerges that threatens global safety and security, Nick Fury, director of the international peacekeeping agency known as S.H.I.E.L.D., finds himself in need of a team to pull the world back from the brink of disaster.

5. Cap Still Uses A Gun

Many fans were not pleased to see Cap wielding a gun when the first trailer for Captain America: The First Avenger was released. In actual fact, we didn't see him use it all that much, and there were very little complaints when the movie was actually released. After all, it made sense...he was on a battlefield during World War II! Well, looks like he'll be using more than just a pistol in The Avengers, as Steve will clearly be getting to grips with some modern day weaponry. Bad ass.

4. Iron Man Uses The Same Armor?

Well, this is a little surprising. Tony Stark has gone through his fair share of armors over the course of two movies, but it looks like he's simply repaired the suit he destroyed in his battle with Whiplash in Iron Man 2 for The Avengers! Whether this is a case of Marvel Studios wanting to maintain some continuity (the character often keeps the same armor in the comics for years at a time after all) or a set up for the debut of a different suit at a later point in the movie is unknown at this point. However, there are a few minor changes, so I'm sure they won't have too much trouble selling the action figures next summer...

3. Mjolnir Has A New Handle...And Thor Has A New Look (Sometimes)

I couldn't help but notice that Thor's iconic hammer has had something of a makeover since his solo movie earlier this year. It's nothing major, but what's up with the decision to make the handle longer? While it's a fairly minor change in the grand scheme of things, it stuck out a bit for me while watching the trailer. Of course, that's not the ONLY change that the God of Thunder has undergone. Looks like he'll be spending a lot of The Avengers with no cape or chainmail sleeves. Of course, Thor's original 616 suit had no arm coverings either while the cape (which he still does seem to sport every now and then) has been removed as it was in The Ultimates. A comic which has seemingly influenced the cinematic universe a fair bit so far.

2. Loki's Weapon

So, what is that exactly? It's clearly not the Cosmic Cube and it looks a fair bit bigger than the largest Infinity Gem which was spotted on the Gauntlet in THOR. Whatever it may or may not be, we see plenty of the destruction it causes and it's clear that it packs one hell of a punch. What's most interesting about it in the trailer though is that the team obviously get their hands on it at some point, and if you think back to when we saw Loki wielding it during filming, you may be able to piece together the sequence of events which lead to his eventual capture...are the scenes at the beginning of the trailer his escape?!

1. The Avengers' Base Is Stark Tower

Avengers Mansion. The Triskelion. The Helicarrier. We all wondered which of those would be the main base for the team. Instead, it looks like we'll be getting Stark Tower as their main base of operation, as it has been for many years in the comics. Whether the heroes will actually live there and how long we'll see it featured in the actual movie is obviously unknown at this point, but it certainly appears as if there's some sort of landing pad for the Quinjet. So, does this mean that Tony Stark has moved from his destroyed home in Malibu to the Big Apple? Again, we just don't know, but I think we can all agree that this is a very eye catching and cool design...different from the comics though. How do you feel about that?
