First off, Matt Damon features in a pretty clever and funny spot for Water.org, in which he announces he's going on strike (from what exactly, you'll just have to see below), until the issue of clean water for all is solved. It's a pretty smart way to include the talking points Damon and the organization want to bring up, without hitting you over the head with it. Also, this is peppered with cameos galore so it's well worth the watch. Next, Joaquin Phoenix swings for the serious in his PETA spot promoting veganism. And we'll just say this, it definitely keeps you watching. Check out both spots below.
