First 'Avengers: Age of Ultron' Trailer Leaked: Watch Hulk Fight Iron Man!

UPDATE: The official trailer is here! Check out the official, non-grainy version below.

The first trailer for "Avengers: Age of Ultron" has leaked!

The official trailer was set to premiere during "Marvel's Agents of S.H.I.E.L.D.," but it looks like someone got to it first and posted the video on TinyPic.

In the trailer, we get to see the whole team in action, including newcomers Scarlet Witch and Quicksilver, who show off their powers a little. We also get our first looks at Ultron in action, as the James Spader-voiced villain first stumbles in and gains strength througout the preview.

Fans will be happy to see some glimpses of an Iron Man/Hulk fight, as Tony Stark will be using his Hulkbuster armor in this sequel to take on a rampaging Hulk.

This trailer seems to be a little different from the one that premiered at Comic-Con, as it doesn't feature the described footage of The Avengers team hanging out together and attempting to lift Thor's hammer. Rather, this one takes a darker tone and uses a creepy cover of "Ain't Got No Strings" from Pinocchio to hammer home the whole puppet theme.

Side note: is anything more disheartening than seeing Captain America's shield broken in two?

Check out the trailer below...we're not sure how long it'll last!
