William Campbell Eubank (born November 15, 1982) is an American director and cinematographer, best known for his work in the science-fiction and horror genres. He made his feature directorial debut with the sci-fi drama "Love" (2011), and went on to direct the sci-fi mystery "The Signal" (2014), the disaster thriller film "Underwater" (2020) and the supernatural horror film "Paranormal Activity: Next of Kin" (2021), a reboot of the long-running series. Like filmmakers Steven Spielberg and David Lynch, Eubank is an Eagle Scout. When Eubank was young, he had an interesting experience with the verisimilitude of cinema. At the time that he first watched the 1974 film "Chinatown," set in the year 1937, Eubank was unaware that it was a period piece, assuming it to have been made contemporaneously in 1937. When he found out it had been made almost four decades after the era it depicted, Eubank came to a realization about film's power. Eubank worked at Panavision Woodland Hills as a camera repair technician and digital imaging technician for eight years; he describes his time at Panavision as serving as his film school. There he worked to promote and provide support for the Panavised CineAlta F900 camera. Using an early SDI capture card and brand-new eSATA drives that had just appeared on the market, Eubank stacked 14 hard drives on top of each other and drilled a hole into a Power Mac G4 in order to create an NLE system on a personal computer that could directly capture 1080p from the F900 camera. When the working result was seen at Panavision, co-workers agreed a shift was about to occur in the industry. Eubank credits the company's kindness to him as being essential to his development as an artist saying "I owe my entire career to those guys".
