Avengers: Age Of Ultron Trailer #2 Officially Released Online

Marvel has officially released its second full-length trailer for Avengers: Age of Ultron.

The sequel to 2012's massively-successful Avengers film, Age of Ultron reunites The Earth's Mightiest heroes in a bid against Ultron, a sentient android created by Tony Stark. As founding members confront the constantly-evolving robot, they will discover new heroes in the form of superpowered twins Scarlet Witch and Quicksilver, and The Vision. Director and screenwriter Joss Whedon also returns to helm the second Avengers outing.

Age of Ultron marks the grand finale of Marvel's Phase Two films, with the more character-focused Ant-Man left to round out its second slate of Avengers films.

You can check out the official trailer below, which originally aired during Monday night's NCAA College Football Playoff Championship Game.

Avengers: Age of Ultron opens on May 1st.
