VIDEO Helpful explanation of the Infinity Stones in the Marvelverse

So what the heck are those Infinity Stones in the Marvel movies? How many are they? What do they do? And why is it such a big deal that the dude with the big chin wants to get them all together?

This video has all the answers.

It comes from the special features on the upcoming home video release of Avengers Age of Ultron and does a great job of breaking down the information we've recieved to date. The mythology has been explored a lot more in recent movies but its great to see significant mentions going as far back as the first Captain America.

There really has been a plan all along, though it's kind of interesting to see this explanation appear on the disk for Age of Ultron, which arguably furthered the universe less than any other recent Marvel pic. It's all set to come to a head in the upcoming two-movie sequence Infinity War, and that's going to be just a bit big.

For right now, Age of Ultron is on DVD and blu-ray in October 2015.
