Robert Downey Jr. Tweets 'Avengers: Age Of Ultron' Set Photo

Robert Downey Jr. is new-ish to Twitter. The world's most famous star joined the social media site on April 11, and has tweeted 10 times thus far, including a plug for former "Iron Man" director Jon Favreau's new movie, "Chef." (Downey has a cameo appearance Favreau's film.) It's his 10th tweet, however, that has geeks of all stripes buzzing: Downey posted a photo from the set of "The Avengers: Age of Ultron." Before fans get riled up, note that the pic isn't as juicy as those set pictures of Aaron Taylor-Johnson and Elizabeth Olsen; instead, it's a shot of Downey and executive producer Jeremy Latcham. Check it out below. "The Avengers: Age of Ultron" is out on May 1, 2015.
