We're now less than three months out from Wonder Woman and it looks like the promotional campaign is starting to kick off in a big way.

This new trailer covers basically the origins of Wonder Woman and the fact that pretty much nobody calls her that, instead using her real name - Diana of Themyscira. You've also got a sword-wielding Robin Wright as Wonder Woman's trainer / possible life-coach and you've also got Chris Pine in there as the hapless American who lands on Themyscira.

The trailer also confirms a few of the rumours that have been circulating online about the plot, namely that poisonous gas and the dawn of chemical warfare is a big part of the story and overall theme.

Right, that's enough filler. Here's the trailer.
