There's now less than two months to go until Avengers: Age Of Ultron hits the big screen - and Marvel Studios just dropped the best trailer yet for the blockbuster.

It begins with glorious aerial cinematography of the Italian Alps, with Scarlet Witch and Quicksilver entering a mountaintop castle to meet James Spader's robotic villain Ultron perched on a throne.

[related]"I was designed to save the world," he tells them, before the action cuts to a sci-fi looking aircraft flying over a US city. "People would look to the sky and see... hope."

He then adds, ominously: "I'll take that from them first."

And just in case we haven't got it yet, he continues: "There's only one path to peace... their extinction!"

Cue collapsing buildings and general mayhem - and it's time for Tony Stark (Robert Downey Jr.) to do a bit of explaining.

"I tried to create a suit of armour around the world, but I created something terrible," he confesses.

And Bruce Banner (Mark Ruffalo) responds: "Artificial intelligence."

There's a bit of bickering between Earth's Mightiest Heroes before the action really kicks off - with highlights including Scarlett Johansson's Black Widow riding a motorbike out of an aircraft, Chris Hemsworth's Thor challenging Ultron to do his worst and Hulk in full-on SMASH mode.

The movie hits UK cinemas on 23 April.
