Here’s an interesting photo gallery: stills from the second season taken by Paul Schiraldi, one of the on-set photographers for Game of Thrones (and a number of other HBO shows, past and present, by the looks of it).
Among the many stills never seen before? This one, taking during a scene that was cut, featuring the murder (by strangling) of Irri. It was something left vaguely mysterious and unclear, though by the final episode the implication was clear enough—but now we can see just how the first thought of staging the scene.
