Sheila writes: Steven Soderbergh may be retired from movies, but he continues to be a very busy man, primarily with his Cinemax show "The Knick." But in the last couple of weeks, he also launched a conversation-starter on his own site, about the issue of "staging" scenes in film. Soderbergh writes that staging "(roughly defined) refers to how all the various elements of a given scene or piece are aligned, arranged, and coordinated." To show what he means, Soderbergh took a film with a high level of visual staging, "Raiders of the Lost Ark," stripped its sound, made it black-and-white, and overlaid the whole thing with the Trent Reznor/Atticus Finch synethized scores for David Fincher films. The result is a fascinating experiment in visual style. Soderbergh writes, "I operate under the theory a movie should work with the sound off."
