Crump directed the feature-length documentary film Black White + Gray: A Portrait of Sam Wagstaff + Robert Mapplethorpe, which premiered in North America at the 2007 Tribeca Film Festival and in Europe at Art Basel. It explores the influence curator Sam Wagstaff, photographer Robert Mapplethorpe and musician/poet Patti Smith had on the 1970s art scene in New York City.

Travelling around the country, Art City: Simplicity takes viewers on a revealing trip into the studios and lives of a group of singular artists. On a desert mesa outside Santa Fe, Richard Tuttle invents his mysterious and marvellously humble forms, made of wire, cardboard, wood. In Taos, Agnes Martin rhythmically repeats extremely simplified images. Near the Santa Monica surf, John Baldessari, aims for successful juxtapositions of photographs and text. In his North Hollywood living room, Robert Williams revels in surreal cartoon imagery. At a cabin in Woodstock, Joan Snyder refines her sensuous art amid a lush forest. Mike Bidlo salutes Duchamp in a SoHo Gallery, while on Sunset Boulevard, Amy Adler reclaims personal history through self-portraits. Through this group of memorable iconoclasts, the creative "act" is there to see and study.
