John Fleck, born May 7, 1951, is an American actor and performance artist renowned for both his television and theatrical work. Over his career, Fleck has appeared in numerous TV series, such as Babylon 5, Carnivàle, Murder One, True Blood, and all modern Star Trek franchises—The Next Generation, Deep Space Nine, Voyager, and Enterprise—making him one of only thirteen actors to achieve this distinction. His film credits include roles in Waterworld, Falling Down, and Velvet Buzzsaw, among others. Fleck is also a celebrated performance artist, noted for being one of the "NEA Four," a group of artists involved in a famous legal battle with the National Endowment for the Arts over the withdrawal of funding on the grounds of alleged obscenity. Fleck’s performance art often blurs boundaries with theater and is characterized by its provocative and experimental nature. In addition to film and TV, he regularly performs self-scripted one-man shows in prominent venues and continues to be a significant figure in both mainstream and avant-garde American entertainment.
