Want a Laugh? Watch 'Avengers: Age of Ultron' Gag Reel (Exclusive)

As has been well documented on late-night talk shows, Robert Downey Jr.’s Twitter, and behind-the-scenes video, Marvel’s mightiest heroes like to get goofy. Really goofy.

Take this exclusive gag reel from Avengers: Age of Ultron. Here we get to see Downey, Scarlett Johansson, Mark Ruffalo, and the rest of the gang flubbing their lines, doing impersonations, and generally joshing about while cameras roll.

And the footage isn’t without some amazing revelations, such as:

—Who knew Ruffalo could do such a dead-on Peter Falk?

—Would you dare mess with the Hulkbuster — even if he wore a “kick me” sign?

—What is Stellan Skarsgård trying to do exactly?

—Why are we laughing so hard at Samuel L. Jackson’s reaction to Johansson missing her mark?

Look for this gag reel and more bonus features when Avengers: Age of Ultron comes out on Blu-ray on Oct. 2. The movie is also out on digital HD and Disney Movies Anywhere on Tuesday (after Labor Day).
