Tonight's episode of Entertainment Tonight featured an extensive report from the set of Marvel's highly-anticipated Phase Two sequel Avengers: Age of Ultron, which shows plenty of new footage, including a brief glimpse of Quicksilver (Aaron Taylor-Johnson) using his super-speed to punch Captain America (Chris Evans) square in the face. We also see Quicksilver's sister, Scarlet Witch (Elizabeth Olsen) using her persuasive mind-control techniques on Black Widow (Scarlett Johansson).

Marvel Studios presents Avengers: Age of Ultron, the epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

In case you have to watch that Quicksilver/Cap punch over and over again, you can do so in one of the looped videos below, and there is also another puzzling bit of footage that should be examined. Towards the beginning of ET's piece, there is a brief glimpse of what appears to be a shadowy figure who may be showing off some Wolverine-style claws, but it's too dark to tell for sure, and the footage only lasts for a few seconds, if that. At any rate, you can take a look at the ET report below, and stay tuned for the full Avengers: Age of Ultron trailer debuting on Thursday, March 6, during the series premiere of American Crime on ABC.
