This one's for all the film nerds out there. We managed to stumble across a bunch of incredibly candid behind-the-scenes snaps from some of the greatest films ever made. The anonymously shot photos manage to capture candid moments between actors, directors, crew, puppets and monsters you'd never imagine you'd get to see. Some of the shots showing how they pulled off big action sequences (the Stay Puft Marshmallow Man destroying NYC!!!!!) are freaking awesome and a rare glimpse into eras of filmmaking that are well and truly history.
