Robert Downey Jr. can't seem to get enough of "Avengers: Age of Ultron". The actor who plays the pivotal role of Iron Man in the film has been giving regular glimpses of the film and his social media handles have become a treasure trove of photos of "Avengers: Age of Ultron" cast members.

Last week Downey tweeted a picture of himself with producer Jeremy Latcham and also shared the snap of chairs given to each of his fellow Avengers. On Sunday, he once again clicked a picture of all his co-stars sitting around a table, which looked like a restaurant.

Apparently, the photo was clicked at a Petersham Nurseries garden restaurant in London suburb of Richmond.

The star studded photo had director Joss Whedon, Chris Hemsworth (Thor) and his wife Elsa Pataky, Scarlett Johansson (Black Widow) and fiancé Romain Dauriac and producer Jeremy Latcham.

Though the fans were thrilled to see the A-listers bonding and having dinner together, Chris Evans (Captain America) and Jeremy Renner (Hawkeye) were missing from photo.

"Avengers: Age of Ultron" is a sequel to 2012 blockbuster "Avengers" which made $1.5 billion at the box office. The sequel's main villain is Ultron, who is reportedly a disturbed robot.

"I'm having a blast with Ultron. He's not a creature of logic - he's a robot who's genuinely disturbed. We're finding out what makes him menacing and at the same time endearing and funny and strange and unexpected, and everything a robot never is," he said of Ultron, who will be voiced by James Spader," director Joss Whedon revealed to EmpireOnline

Apart from the "Avenger" stars there will be new cast members joining the film. They include Baron Wolfgang von Strucker, Scarlet Witch (played by Elizabeth Olsen), and Quicksilver (Aaron Taylor-Johnson).

Regarding the addition of more people Whedon said, "I fiercely dislike the idea of just throwing in more people for the sake of doing that," Whedon told the publication. "But last time I had all of Earth's Mightiest Heroes versus one British character actor, and I needed more conflict."
