Watch a Twelve-Second Teaser of The Avengers
Here's a tricky one: Those who have seen Captain America will already have seen this footage, as a longer version of the teaser plays in theaters after the movie. Those who have not seen Steve Rogers get recruited will maybe want to avoid this clip, as it includes the last scene of the movie. But if you're desperate to see the whole gang together, fast-forward to the 35-second mark. Cool SitRoom, guys.
