Robert Downey Jr. and Mark Ruffalo share ‘Avengers: Age of Ultron’ set pics

“The Avengers” have re-assembled, and they love to take selfies.

Fans are getting their first official glimpses of Marvel's highly-anticipated “The Avengers: Age of Ultron,” courtesy of co-stars Robert Downey Jr. and Mark Ruffalo — but don't expect to see Iron Man, Hulk, Thor, Captain America, Black Widow, Nick Fury, Quicksilver or Scarlet Witch in action. These are basically just on-set selfies.

Among numerous shots tweeted by Downey Jr. is this pic of himself and executive producer Jeremy Latcham in their secret superhero costumes. 


Meanwhile, Ruffalo also took to the Interwebs to post a handful of on-set images, along with this tweet which is sure to get Marvel fans' blood pumping:
