Avengers: Age of Ultron (2015)

The first US teaser from October 2014 uses a disturbed Pinocchio-song association and Ultron's damaged appearance to turn a familiar superhero team into people facing their own creation. The ominous musical idea binds the fragments tightly. The feature gives James Spader more personality and the Avengers more arguments, but also juggles jokes, new arrivals and future-franchise business. The teaser wins this particular contest through the concentration of its mechanical menace.
