Green Lantern: Nathan Fillion plays Guy Gardner, aka Green Lantern, a man with a special ring capable of conjuring anything he can imagine in physical space. In the trailer he uses it to keep a door closed from a baying mob after they're shown targeting Superman - one angry crowd member even throws a cup at Superman's head.

The trailer for James Gunn's upcoming Superman film showcases a host of things from the new movie, including kaiju, plenty of action, and a look at all of our new heroes suited up. But its greatest trick is making you feel hope again.
