'Iron Man 2' set photos and video pop up online!

It's a day filled with set pics and videos. Besides plenty of pics from Sylvester Stallone's "The Expendables," I also came across some set pics and a set video from Jon Favreau's upcoming sequel "Iron Man 2."

Yep, the follow-up to the brilliant "Iron Man" has started principal photography, and the folks at Spoiler TV just posted a bunch of pics of Robert Downey Jr., Don Cheadle and Gwyneth Paltrow. Check one of the stills on the left and another one after the jump.

In the video below, you'll also get to see the stars of the film, including Sam Rockwell and Garry Shandling. Also starring in the film are Scarlett Johansson and Samuel L. Jackson, but they haven't been spotted yet.

And if all this is not enough for you, here's the latest from Jon Favreau's Twitter feed: "First day went great. I've never worked on a sequel before. It's like we picked up where we left off" and "Day 2. Slept like a rock. Finally. Not used to these long hours."
