Circle of Love (1964)

Having previously been filmed under the same title by Max Ophüls, Arthur Schnitzler's once-controversial play "Reigen" got an appropriately scintillating update courtesy of swinging-sixties eroticist Roger Vadim. Jane Fonda, Anna Karina, and Jean-Claude Brialy are among the bed-hopping coterie of soldiers, prostitutes, maids, actors, and aristocrats who swap lovers amid the opulence of pre-World War I Europe, captured in sumptuous color by celebrated New Wave cinematographer Henri Decaë.
