In regards to the somewhat subjective idea of influence as it pertains to any given element of cinema the list of filmmakers whose names you’ll hear is, for the most part with a few variables, the same. From the perspective of an outsider/spectator all we can ever truly ascertain about influence is little more than an educated assumption, unless heard straight from the horse’s mouth. One of the variables on a given list of names of influential filmmakers is the partnership of Michael Powell and Emeric Pressburger. That is, unless, you’re talking directly to someone like Martin Scorsese.
A good deal of this is the difference in distinction between remaining part of the cultural conscious and having a fingerprint on modern filmmaking. Whether that fingerprint has been smudged and unrecognizable through dilution over time it’s still felt to those who are familiar. Those like Martin Scorsese, who may be the all-time champion of The Red Shoes having headed the painstaking digital restoration to make the film look as it currently does; which is nothing short of gorgeous. Why would he do that? Because it, along with other Powell films like Peeping Tom (also unlike most films of its time and closely resembling films of ours), mean that much to him as an artist and fan of film; and if he can make you feel the same then he’ll do what he can.
