Gregory Dark (born Gregory Hippolyte Brown on July 12, 1957 in Los Angeles, California) is an American film director, film producer, music video director, and screenwriter. Dark is one of the few adult film-makers to successfully transition into mainstream Hollywood film-making. He has also been credited as Alexander Hippolyte, as Gregory Brown, and as The Dark Brothers.
Dark began his career as a fine artist of both paintings and conceptual art and installations. After graduating with an M.F.A. from Stanford University, he moved to New York City to pursue graduate studies in film at New York University.
From the mid-1980s through the mid-1990s, Dark directed hardcore and softcore adult films. His work from this period influenced the current "Alt porn" genre. Dark directed or produced more than 30 action films and erotic thrillers as head of production for Axis Films, a B movie company, from 1987 to 1995. Dark's erotic thrillers in the early 1990s such as Animal Instincts I and II, Body of Influence, and Mirror Images II featured Shannon Whirry in various stages of undress.
