Extended 'Avengers: Age of Ultron' Trailer Premieres (VIDEO)

Marvel is keeping the hype train rolling for Avengers: Age of Ultron, the movie that is very likely to be the biggest thing happening in cinemas in 2015, if the record-breaking box office of 2012's The Avengers is any indication. The latest trailer is an extended version of the world premiere launch trailer, and it features some new clips.

Of course, many of the new clips in this extended trailer are easy to miss. A new shot of Quicksilver here, a new clip of Ultron there, and even a few extra shots from some of the big battle scenes. And throughout it all, we still get that creepy, ominous version of "I've Got No Strings," which is far more unsettling than any song from Pinocchio probably should be. Still, it's all pretty cool stuff. May needs to hurry up and get here.
