Here's a first look breakdown with some speculation and comparisons to the comics.
It's no secret that Gorr the God Butcher is going to be an antagonist in this movie. He's being played by Christian Bale and really stands out as one of Thor's deadliest foes.
This is pretty much where his head is at...
Why he's called the Butcher...
There's a scene in that trailer thats ripped right from a comic page that I thought was really cool.
One of Gorr's victims. The God Butcher ain't no joke!
