Joss Whedon's announcement at San Diego Comic-Con that his 'Avengers 2' takes its official title from the 'Age of Ultron' comics sent an explosion of excitement throughout the buzzing Hall H, but apparently this plan was in the works for months prior. As Marvel Studios head Kevin Feige reiterated a point Whedon made, the movie won't follow the classic storyline and Ultron origin, instead utilizing plot points from various 'Avengers' adventures.

In an interview with Empire magazine, Feige clarified (just a bit) Marvel's intent in using Ultron as the primary antagonist for the upcoming sequel:

We came up with a few titles, but every month a new comic book appeared, and that's a great title. 'Age Of Ultron' is a great title. We had a few other 'of Ultrons', but that was the best one. So we're borrowing that title, but taking storylines from decades of 'Avengers' storylines.

Whedon has already included famous siblings Quicksilver and Scarlet Witch in his current story treatment, but one possible way the plot could separate itself more from the comics is, perhaps, the inclusion of fan-favorite Loki (Tom Hiddleston).

Though Whedon already stated that the beloved 'Thor' and 'The Avengers' villain won't appear, Feige and Marvel acknowledge the character's continuing popularity with the moviegoing crowds. "We think Loki could be the 'big bad' for us, for a long time," he said.

Though, while this is no official confirmation of anything, Loki must first survive the events of 'Thor: The Dark World' and the wrath of Thor himself. If you care to gain some more spoiler info from our Comic-Con panel recap, click HERE.
