Comic Con 2013 | experience it all.

At Comic Con 2013 in San Diego, Marvel packed Hall H to share with fans new footage from its upcoming slate of super hero flicks including Thor: The Dark World and Captain America: The Winter Soldier. At the very end of the panel, surprise guest Joss Whedon took the stage to announce the title of his next Avengers movie and it is Marvel’s The Avengers: Age of Ultron. In case you didn’t know, Ultron is a famous Marvel supervillain that is a robot with massive amounts of artificial intelligence. The nearly indestructible foe will prove to be a worthy villain in the Avengers sequel due out May 1, 2015. Thanos, the other-worldly villain teased during The Avengers‘ credits sequence, will likely make a grand appearance before A2 now that we know Ultron is the big bad our heroes will face in the sequel.

In addition to naming the next Avengers film, Marvel touted another Phase 2 flick in the works: James Gunn’s Guardians of the Galaxy. Due August 1, 2014, Galaxy stars Chris Pratt (Zero Dark Thirty) as Peter Quill aka Star-Lord, Zoe Saldana (Star Trek Into Darkness) as Gamora, Dave Bautista (Riddick) as Drax the Destroyer, Lee Pace (The Hobbit) as Ronan the Accuser, Michael Rooker (The Walking Dead) as Yondu, Karen Gillan (Doctor Who) as Nebula, Djimon Hounsou (Gladiator) as Korath, Benicio del Toro (Traffic) as The Collector, John C. Reilly (Chicago) as Rhomann Dey, and Glenn Close (Fatal Attraction) as Nova Prime.

Actual footage from these Marvel movies has yet to be released to the general public; for now, eye the official logos in the gallery below.

Bonus! Actor Tom Hiddleston crashed the Thor part of the panel in-character as Loki. Watch him command the crowd in an entertaining clip embedded after the break.
