The third trailer for “Avengers: Age of Ultron” was unlocked on Wednesday. Viewers were happy to see tons of new footage from the superhero flick in the two-minute and 18 second trailer.

Fans unlocked the trailer by tweeting #AvengersAssemble for over four hours on Twitter. The challenge was a surprise for Marvel followers, who anticipated watching the new video during its scheduled Thursday premiere on ABC's new drama, “American Crime.” However, fans are likely thrilled that they got to watch early. Since it’s pretty easy to be distracted by the appearance of Vision at the end, we decided to point out some of the moments that you may have missed the first time around.

Avengers Tower – At the 40-second mark, we see the new Stark Tower has left most of Tony’s (Robert Downey Jr.) name off. The building was originally damaged in “The Avengers,” leaving only the “a” from “Stark” standing. It seems Tony decided to keep his name off the building.

Romance – Black Widow (Scarlett Johansson) and Hulk (Mark Ruffalo) were getting awfully close around the one-minute point in the trailer. Could they be a real couple or is this another one of Natasha’s distraction techniques?

Who Are They Fighting? – The Avengers are seen fighting alongside each other at the 1:09 mark. It’s a supercool shot of the whole team, but look to the right. They’re fighting soldiers. Has the military turned against them? Is this fallout from Hydra’s infiltration of S.H.I.E.L.D. in “Winter Soldier”?

Fury – Nick Fury (Samuel L. Jackson) appears at 1:18, and he’s actually pretty hard to miss. However, some fans might forget that only a select few are allowed to know he is alive. He’s taking a serious risk by meeting with the group, but apparently, all the Avengers are allowed in on the whole “Fury’s alive” secret. Now if only someone could tell them about Coulson (Clark Gregg)…

Black Widow In Trouble – Natasha is not doing too well around 1:39. She appears to be in pain as someone behind her – we’re guessing Scarlet Witch (Elizabeth Olsen) – waves their hand and some red bursts of light appear to go into Black Widow’s head. When Natasha opens her eyes, they're glowing red.

Quicksilver vs. Captain America – At 1:40, it’s almost too quick to see, but that’s Quicksilver (Aaron Taylor-Johnson) taking down Captain America (Chris Evans) with a punch to the face. It looks like Quicksilver and Scarlet Witch won’t be easy for the Avengers to defeat.
