Have you not seen Captain America yet? Well Marvel Studios and Paramount want to make sure you do…and stay all the way through the credits.
To do this they’ve released a bit of the final scene from Captain America online along with a very brief snippet of The Avengers teaser that follows the credits.
It’s not the complete final scene. It’s cut short to not completely spoil the movie (and c’mon, who didn’t know that Cap ends up in modern times?), and the teaser is just a couple seconds… just enough to get you to stick through the credits to see the whole thing.
