"BLACK GOLD is the story of the coverup of the century - of the boss atop a trillion-dollar industry who discovered a shocking truth 40 years ago, created a black ops conspiracy to hide the evidence, and would stop at nothing to keep the money flowing, while the world burned..." Gullette produced The 8 with Sarah Riggs and Blaire Dessent; the film was selected for the 2010 Berlin Film Festival.

He wrote "New York Stories" for Donna Karan's DKNY, and directed the "Von Hummer the 1st" series of promotional spots for VH1, starring James Urbaniak.

Our re-reading of the Manson myth is also carried by Peter Fonda, rock author Lizzy Goodman, VIBE editor Desiree Thompson, Woodstock founder Michael Lang, John Fogerty of Creedence, and Tariq Trotter of The Roots."
