The Making of The Avengers - Behind The Scenes Footage & Photos

TheIrishAvengerCBM has kindly edited all the official B-Roll footage clips into one nice convenient single reel. Originally made available as promo clips before the film's release - but I think it's more interesting (and less spoilery) to watch them after. They feature tons of cool filmmaking stuff like fight choreography, stunt & green screen work, actor blocking, fussing with costumes & make-up as well as the cast and crew in great candid casual moments. I've also "assembled" gallery of  behind the scenes photos bellow.
