The teaser for Avengers: Age of Ultron was supposed to drop with next week’s episode of Agents of S.H.I.E.L.D., but there was a leak last night (which Marvel blamed on HYDRA), so Marvel just went ahead and officially released it early.

At the moment, I’m kind of embed-challenged, but you can see the trailer by following that link above. According to folks who were there, this is basically the same footage that ran at SDCC a couple of months back, and it’s pretty cool. It comes across as pretty dark, though I don’t expect the movie to be quite so bleak as it appears here. Lots of neat images: Hulkbuster, creepy early-Ultron “puppet” (complete with the creepy, processed Pinocchio song), a little bit of Scarlet Witch and Quicksilver (official MCU versions), and a rather iconic image of Cap’s shield, shattered…

…And Andy Serkis playing some unidentified character, which along with a couple of other quick images in the trailer, has spawned yet another Doctor Strange casting rumor, unlikely as it might be. I do, however, think this one is my favorite; since I’m sure Mr. Serkis could pull it off with just the right balance of charisma and otherworldly weirdness in a way that all those marquee idol pretty faces being bandied around couldn’t match.

So, now that this leak and early release happened, what does this mean for Agent Coulson and company next week? No matter how good it’s been this year, it could’ve used the ratings boost the trailer reveal would’ve given it…or, given how crafty Marvel seems to be, I wonder if the leak wasn’t planted from the start, leading Marvel to sneak out some other, juicier piece of footage/information on Tuesday night? Maybe sticking some titles to all those unidentified Marvel movie dates out there to match the big DC announcement last week? Hints at Captain Marvel or Black Panther? Something else cool nobody’s even thought of yet?

One can only hope. It’s a cool time to be a comic geek.
