Robert Downey Jr. is getting into character as Tony Stark/Iron Man! The actor tweeted out his first picture [1] from the set of Avengers: Age of Ultron [2] this week alongside executive producer Jeremy Latcham. Since I love any and all Downey Jr. news, this is big stuff. The movie is set for a May 1, 2015, release, so look forward to even more pictures until then!
