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.
