Walt Disney Pictures and Marvel Studios have released 20 minutes of behind-the-scenes B-Roll footage for Marvel’s The Avengers which you can watch in four parts below! An incredible new image of The Hulk has also come online and you can click on it to see a much bigger version.

In related news, we talked to Robert Downey Jr. today who dropped this bit: “We’re actually not done shooting. We’re shooting another scene tonight. I’m not kidding.” The press got to see the film yesterday and there was an extra scene in the middle of the end credits, so this is presumably for a scene at the very end of the credits.

Coming to 3D, 2D and IMAX 3D theaters on May 4, the Joss Whedon action adventure stars Robert Downey Jr., Chris Evans, Mark Ruffalo, Chris Hemsworth, Scarlett Johansson, Jeremy Renner, Tom Hiddleston, Stellan Skarsgård, Cobie Smulders and Samuel L.
