Between Avengers and Halo, this was a huge week for trailers — though we can't blame you if you missed everything else in all the sci-fi and comic-book commotion. We've rounded up eight of this week's best trailers below so you can see everything that's coming up all in one place.
Marvel planned to debut the Avengers: Age of Ultron trailer during Agents of SHIELD next Tuesday, but apparently that plan didn't work out. Shortly after a poor quality version of the entire trailer leaked online, Marvel decided to publish an official teaser trailer on YouTube. The two-minute video shows the full team in action and includes a look at the Hulkbuster armor, a super strange version of "I've Got No Strings," and, of course, Ultron, as voiced by James Spader in what sounds like a wonderfully creepy performance. The film is headed into theaters on May 1st, 2015 in the US.
