Joss Whedon has sought to make The Avengers unique, and the latest way was shooting a scene for the movie after the movie premiered. According to HitFix, the entire team (from Robert Downey Jr. to Scarlett Johansson) used the opportunity of the occasion to shoot one last scene. Apparently it’s tough getting a dozen notable names in the same room.

There’s no telling what the scene entails, although there’s speculation from Mark Ruffalo‘s press conference statements that the scene will appear at the end of the movie. It’s not the stinger; the audiences on Wednesday night already saw that.

It’s definitely an interesting move. Or a really expensive way to get one audience to want to see the movie again. It’s not like they need it. The movie is already tracking for a $135m opening. Let’s see all of them try to get in the same room after that.
