"Avengers: Age of Ultron" is out on DVD and Blu-ray next month.
Ahead of its release, Yahoo Movies debuted a sneak peek at the gag reel and bloopers from the film.
We see Samuel L. Jackson's Nick Fury get smart with Black Widow (Scarlett Johannson), Tony Stark's Hulkbuster suit challenging his comrades to "kick" him, and a long look at a scene with Hawkeye (Jeremy Renner) and Quicksilver (Aaron Taylor-Johnson).

The best thing about this blooper reel, though, is watching Mark Ruffalo try to pronounce some crazy scientific term over and over. He laughed on the outside, but something tells us he was really pretty annoyed on the inside!
"Avengers: Age of Ultron" will be available on digital HD September 8 and Blu-ray October 2.
