The press junket for Avengers: Age of Ultron kicked off at Walt Disney World Studios this weekend in Los Angeles as part of the Marvel super groups’ worldwide press tour. To the delight of fans everywhere, the films stars weren’t just merely in attendance answering questions from press and bloggers. The actors were tweeting and instagramming up a storm across social media, too. We did a little bit of internet stalking ourselves and rounded up highlights of the day as seen through the eyes of Robert Downey Jr., Chris Evans, Jeremy Renner, Chris Hemsworth, and Mark Ruffalo. From foreboding Civil War jokes to hangs with Scar Jo, Earth’s mightiest heroes looked to be having a blast yesterday.

Avengers, assembleee!

Joss Whedon was joking around with Daredevil’s Executive Producer Steven DeKnight:

While Jeremy Renner learned that indeed “mommy bloggers” do exist:

Just sat with an army of “mommy bloggers” Didn’t know that was a thing til now, but I LOVED it!! #aou #marvel

Mark Ruffalo shared photos with the head honcho of Avengers 1 and 2, Joss Whedon, along with Black Widow herself, Scarlett Johansson:

Nothing could have beaten RDJ’s jokes poking fun at the eventual rivalries that will take place in Captain America 3: Civil War, though:
