Avengers: Age Of Ultron - First Good Look At Ultron On EW Comic-Con Cover

Avengers: Age of Ultron is on the cover of the newest issue of Entertainment Weekly, giving us our first look at the villainous Ultron in the film.

They cover shows Iron Man (Robert Downey Jr.) and Captain America (Chris Evans) standing in front of the sentient AI's physical form, with an army of Ultron drones marching forward from the background.

Speaking about the film's story and themes, the stars say it will be about how the Avengers are forced to deal with the negative side effects of heroism.

"The downside of self-sacrifice is that if you make it back, you've been out there on the spit and you've been turned a couple times and you feel a little burned and traumatized," says Downey.

The preview for the issue also reveals Ultron's origin in the film. Tony Stark creates Ultron as a force for good, a tool to allow him and the other Avengers to take a break without letting the world down. Obviously, things don't go as planned.

"Ultron sees the big picture and he goes, 'Okay, we need radical change, which will be violent and appalling, in order to make everything better'; he's not just going 'Muhaha, soon I'll rule!'" director Joss Whedon says. "He's on a mission. He wants to save us."

Avengers: Age of Ultron comes to theaters May 1, 2015.
