If there were any doubts about the casting of James Spader as the villain in Avengers: Age of Ultron, this new extended trailer should put them to bed because for the first time we're genuinely threatened by him.

The newest extended trailer comes courtesy of Samsung, who if you watch carefully have a tiny bit of branded lashed into the background of an as yet unidentifiable scene (what, you thought blockbuster movies funded themselves?), and is pretty much the same as the one we've already seen but with extra shots of our Avengers in separate locations doing battle with Ultron and others as well as an extended introduction from the party in Tony Stark's gaff that all goes wrong when Ultron makes his first big appearance.

We also finally get confirmation that the mystery woman chilling with Thor is not Natalie Portman's Jane Foster but Claudia Kim playing an as-of-yet unidentified role but Buzzfeed seem to think it's Suzi Endo, a Stark Industries scientist who has something to do with Ultron, which sounds like a good guess pretty good to us.

Avengers: Age of Ultron is scheduled for release in May 2015, and we are still very bloody excited about it.
