These photos were taken at Lee Marvin's "Point Blank" wrap-up party at "The Zoo" club, Los Angeles, 1966
The woman dancing with McQueen is his first wife, dancer/actress/singer Neile Adams
Charles Bronson and Warren Oates were also at this party. I can't identify anybody else other than the ones already identified on this page:
