Black White + Gray: A Portrait of Sam Wagstaff and Robert Mapplethorpe is a 2007 American documentary film directed by James Crump. The film chronicles the symbiotic relationship between Sam Wagstaff, an American museum curator and collector of fine art, and Robert Mapplethorpe, the American fine art photographer whose controversial images were at the center of debate about public funding for the arts and the culture wars of the late 1980s. The film also explores the relationship both men shared with poet/musician Patti Smith in the New York art world of the 1970s.
