The film’s director, Joss Whedon, made the announcement, in his typical tongue-in-cheek manner, in an email to Whedonesque -
Hi Pumpkins, joss here.
Tomorrow we start shooting (I THINK I’m legally permitted to say that). Day one. That’s right. We’ll be shooting the pivotal death/betrayal/product placement/setting up the sequel/coming out scene, at the following address:
[Marvel Lawyers rush in, take Joss's keyboard, blowtorch a picture of his family like in "Stormy Monday", drink his milkshake, leave the seat up, fluff his pillows, violently unfluff his pillows, leave]
As you can see from Whedon’s email, it is a bit unclear as to where the cameras will be when they start rolling. The production is set to do a major portion of filming at Albuquerque Studios in New Mexico and Universal Studios in LA. There is also some location work scheduled for New York City and Cleveland, Ohio. Granted, Samuel L Jackson, Chris Evans and Clark Gregg were all in Manhattan yesterday shooting some pick up shots for Captain America, but that doesn’t necessarily mean that The Avengers will begin production there tomorrow.
The Avengers will feature Robert Downey, Jr. as Tony Stark/Iron Man, Chris Hemsworth as Thor, Mark Ruffalo as Bruce Banner/The Hulk, Evans as Steve Rogers/Captain America, Jackson as Nick Fury, Scarlett Johansson as Black Widow, Jeremy Renner as Clint Barton/Hawkeye, Cobie Smulders as Maria Hill, Gregg as SHIELD Agent Coulson, Tom Hiddleston as Loki and Stellan Skarsgård as Erik Selvig.
The Avengers will be hitting theaters on May 4, 2012.
