Marvel's 'Agents of S.H.I.E.L.D.' is currently flying through it second season, amassing between 4 and 5 million viewers per episode. That number is about to explode, however, with the recent announcement that the sixth episode, 'A Fractured House', will contain the first trailer for 'The Avengers: Age of Ultron'. If that news wasn't enough, the announcement came via Marvel's official Twitter page, with an accompanying picture of some of the cast.


The picture shows (left to right) Chris Hemsworth (Thor), Chris Evans (Captain America), Jeremy Renner (Hawkeye), Robert Downey, Jr. (Iron Man) and Don Cheadle (War Machine). Cheadle's presence in the picture shows just how much writer/director Joss Whedon is shaking up the 'Avengers' formula by adding even more faces to the group. 'Captain America: The Winter Soldier' revealed that Aaron Taylor-Johnson (Quicksilver) and Elizabeth Olsen (Scarlett Witch) would be joining in the fight, but supposedly they're going to need all the help they can get when facing off against a giant techno-God.

Ultron, voiced by James Spader, has received an updated origin story for the Marvel Cinematic Universe. The original character was created by Ant Man in the comics, yet as that character (played by Paul Rudd) will not appear onscreen until July, 2015, many fans have settled on the possibility that Robert Downey, Jr's Tony Stark will create the villain, as concept art resembles the design of the Iron Man suit. Originally speculated to be Jarvis (Stark's Artificial Intelligence service and butler, played by Paul Bettany) gone rogue, it was revealed in February, 2014, that Bettany would be playing the role of The Vision in 'Age of Ultron'.

We may receive some of the answers to these questions on Tuesday, when 'Agents of S.H.E.I.L.D.' next airs, although it is more likely that we'll be left scratching our heads even more. The second phase of the Marvel Cinematic Universe is set to end on 24th April, 2015, when 'Age of Ultron' is released, with phase three beginning on 17th July, 2015, with 'Ant Man'.
