UPDATE: Marvel have now officially released the trailer...
Original Story: Leaked images grabbed from next week's debut Avengers: Age of Ultron trailer have revealed the designs of villain Ultron (James Spader) and the Hulkbuster armour worn by Iron Man (Robert Downey Jr).
The low-res images were found by user Pasto over on ComicBookMovie.com, though quite how has yet to be revealed, meaning it could yet be proved fake. That said, the images would appear to be legit.
You can see the image below...
Iron Man's Hulkbuster armour - designed obviously to bust, or try to bust, Mark Ruffalo's Hulk - was first revealed in concept art from the earlier this year. The battle between the superheroes is said to take place in Johannesburg.
Ultron meanwhile looks different to the first revealed look as seen in the header image, but it has been well publicised that he would undergo many changes in look and that some would be more human-like to help convey James Spader's performance.
It was announced earlier today that the first Avengers: Age of Ultron teaser trailer will be revealed next Tuesday, 28 October in the US, which would be first thing in the morning for us in the UK on the Wednesday.
Avengers: Age of Ultron will be released on 24 April 2015.
