Director Joss Whedon reveals that Robert Downey Jr.'s Tony Stark is obsessed with creating a "perfect peace" in a new preview for Avengers: Age of Ultron, which hits theaters on May 1. Producer Kevin Feige is also on hand to explain Tony's current state of mind, and how he believes he would be more efficient if he was not required to be in the Iron Man suit all the time. This leads to the creation of the villainous Ultron. We also hear from Robert Downey Jr. himself and Chris Evans, who teases that Ultron has various parts of Tony Stark's personality embedded within him.

Marvel Studios' Avengers: Age of Ultron is the epic follow-up to the biggest Super Hero movie of all time, 2012's Marvel's The Avengers. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth's Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to the Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

In addition to this preview, we also have three more TV spots from this Marvel Phase Two sequel, which also stars Scarlett Johansson (Black Widow), Chris Hemsworth (Thor), Jeremy Renner (Hawkeye), Mark Ruffalo (Hulk), Cobie Smulders (Maria Hill), Samuel L. Jackson (Nick Fury), Aaron Taylor-Johnson (Quicksilver), Elizabeth Olsen (Scarlet Witch) and Paul Bettany (Vision). The sequel has big shoes to fill, since Marvel's The Avengers took in a record-breaking $207.4 million in its opening weekend back in 2012, en route to a $1.5 billion worldwide haul.
