How do you turn a naked woman into a nude? “Crazy Horse,’’ the 39th film from the legendary documentarian Frederick Wiseman, prowls the Paris nightclub of the title looking for answers. It’s the third in Wiseman’s dance movies (the other two being 1995’s “Ballet’’ and 2009’s “La Danse: The Paris Opera Ballet’’) and the first to explore the more eroticized forms of the medium.
Wiseman, of course, could take his camera into a down-market strip club and come out with a film about the mechanics of titillation rather than titillation itself. It’s not that “Crazy Horse’’ isn’t a turn-on, just that sex is beside the point for this filmmaker. His abiding interest is in the ways that human beings work together, his famous fly-on-the-wall shooting style revealing the constant struggle to connect and create. Wiseman’s are the movies to show to the aliens when they arrive.
