Sometimes the Avengers just fail to assemble correctly. But that's half the fun! Marvel's "Avengers: Age of Ultron" has its digital release this Tuesday, September 8, and it's out on DVD/Blu-ray on October 2. One of the many extras coming with the release is a gag reel, and you can watch it now in the video below.

Several stars are showcased in the bloopers, including Chris Evans, Scarlett Johansson, Robert Downey Jr.,Chris Hemsworth, Samuel L. Jackson, Stellan Skarsgård, and Mark Ruffalo. Sam Jackson closes the video with a strong mock smackdown to Scarlett for going "all stealth mode, motherf--ker" out of the frame. Stellan has a weird line about a swimsuit. But Mark basically owns the gag reel with his struggle to get through Dr. Banner's unpronounceable dialogue and his random but perfect "Can I ask you something?"Columbo impression. Peter Falk would be proud, man.
